We are delighted to announce that the 3rd International Electronic Conference on Atmospheric Sciences will be open for discussions from 16 to 30 November 2020.

**All participants of ECAS2020 are welcome to submit the extended work to the Atmosphere Special Issue "**Selected Papers from the Third International Electronic Conference on Atmospheric Sciences".

Welcome from the Chair

Dear Colleagues,

You are cordially invited to participate in the 3rd International Electronic Conference on Atmospheric Sciences. With this meeting, we hope to build on the first two versions of the conference. We concede that sharing our work face-to-face with our colleagues is preferred, however, the COVID-19 crisis forced many conferences to postpone or cancel their meetings. Technology is continuously improving the virtual experience and we hope to take advantage of the latest developments in order to create a quality online meeting.

For the third electronic conference in atmospheric sciences, the range of topics will remain more general, but we would be open to future meetings or subject areas having a thematic topic of importance. During the last few decades, great strides have been made in all general areas of atmospheric science. We have seen the proliferation of remote sensing technologies and techniques for their use in research and forecasting. We have seen advances in the understanding of synoptic and dynamic meteorology which have improved weather forecasting. Advances in the capabilities of atmospheric modelling as well as increases in computing power have enhanced our understanding of atmospheric behaviors on all time and space scales. Additionally, there have been discoveries related to the behavior of smaller-scale systems, especially those that interact with human activity, health, and economics. These have inspired techniques for warning people that these events could affect them. The increased understanding of interannual and interdecadal variability in climate has also led to the development of long-range forecasting and projection. In conclusion, this conference will be organized around the following general and related themes which correspond to the Atmosphere journal.

Aerosols
Air Quality
Air Quality and Human Health
Climatology
Meteorology
Biometeorology
Atmospheric Techniques, Instrumentation, and Modelling
Biosphere / Hydrosphere / Land-Atmosphere Interactions
Upper Atmosphere
Planetary Atmospheres.

Accepted papers will be published in the proceedings of the conference in MDPI’s online journal, Atmosphere Special Issue "Selected Papers from the Third International Electronic Conference on Atmospheric Sciences" after peer review and enjoy 20% discount on processing fees.

sciforum-035225	A 15-Year Climatology of Desert Dust Episodes in the Broader Mediterranean Basin Maria Gavrouzou, Nikos Hatzianastassiou, Antonis Gkikas, Nikos Mihalopoulos Submitted: 24 Aug 2020 Abstract: Show Abstract	Maria Gavrouzou, Nikos Hatzianastassiou, Antonis Gkikas, Nikos Mihalopoulos	N/A	N/A	Show Abstract Comment
Dust is the Earth’s most abundant aerosol type, mostly originating from great deserts (Sahara, Taklimakan, Gobi, Middle East), but also from agricultural and construction activities. The emitted dust remains in the atmosphere from a few hours up to several days, while under favorable conditions is transported far from its sources. During this transport, the physical and chemical properties of dust can change, thus affecting its action as Cloud Condensation Nuclei (CNN) or Ice Nuclei (IN) as well as its interaction with radiation, consequently modifying the radiation and energy budget of the areas affected by the dust transport. There is need for improving scientific knowledge about dust transport, especially over areas like the Mediterranean basin (MB), which is close to the Sahara, Middle East, and Arabian deserts, and frequently undergoes dust transport, resulting in dust aerosol episodes (DAE). In the present study, DAEs in the broader MB are investigated over a 15-year (2005-2019) period using contemporary MODIS Collection 6.1 and OMI OMAERUV satellite data and a satellite algorithm applying a thresholding technique on selected aerosol optical properties. The algorithm operates on a daily and 1°x1° pixel level basis, first identifying the presence of dust, and consequently requiring the presence of unusual high dust loads, i.e. dust episodes. Apart from the presence of pixel level DAEs, an extended spatial coverage is also required. Thus, a specific day is characterized as a Dust Aerosol Episode Day (DAED), when at least 30 episodic pixels exist. According to the algorithm results, 166 DAEDs (116 strong and 50 extreme) took place in the MB from 2005 to 2019. The greatest part of DAEDs occurred in spring (47%) and summer (38%), while a different seasonality is observed for strong and extreme episodes. The interannual variability of DAEDs reveal a decreasing trend, which is not statistically significant.
sciforum-034523	A Preliminary Study of Winter Atmospheric River’s Precipitation Characteristics Using Satellite Data over Galicia (NW Spain) Elham Ghasemifar, Jorge Eiras-Barca, Iago Algarra, Alexandre M. Ramos, Manuchehr Farajzadeh, Raquel Nieto, Luis Gimeno Submitted: 05 Aug 2020 Abstract: Show Abstract	Elham Ghasemifar, Jorge Eiras-Barca, Iago Algarra, Alexandre M. Ramos, Manuchehr Farajzadeh, Raquel Nieto, Luis Gimeno	N/A	N/A	Show Abstract Comment
This brief research report is aimed to make a first approach to the study of the type of precipitation associated with a set of atmospheric river (AR) events over the Atlantic region of Galicia. Fifteen ARs that made landfall in the Spanish region of Galicia have been analyzed using the 2B-GEOPROF and 2C-PRECIP-COLUMN from the CloudSat cloud profiling radar (CPR). An estimation of the relative ratio between warm and cold precipitation associated with each event is provided. Broadly speaking, cold precipitation accounts for 80% of the total. This value is slightly higher than the already stated for Pacific AR events. However, similar mean rain rates (0.35 mm/h for the warm precipitation and 1.16 mm/h for the cold counterpart) to those reported by the literature have been obtained. In the absence of a more comprehensive and conclusive statistic, it seems that cold precipitation is predominant along the central axis of a well-developed AR. In this central core of the AR, the bulk of the moisture remains in the lower levels, and the freezing level (FL) is low. According to these results, the interaction between the warm conveyor and the cold conveyor belt may eventually raise the FL to upper levels, leading the warm fraction to play a more important —even though still secondary— role.
sciforum-035009	Affectation and Rainfall Contribution of Tropical Cyclones in Puerto Rico from 1980 to 2016 José Carlos Alvarez, Rogert Sori, Albenis Alarcón, Raquel Nieto, Luis Gimeno Submitted: 18 Aug 2020 Abstract: Show Abstract	José Carlos Alvarez, Rogert Sori, Albenis Alarcón, Raquel Nieto, Luis Gimeno	N/A	N/A	Show Abstract Comment
This study investigated the number of tropical cyclones (TCs) that affected Puerto Rico during the June-November hurricane season in the period 1980-2016, and their contribution to total precipitation. Special attention was dedicated to assessing the role of atmospheric-oceanic teleconnections in the formation of TCs that affect this island. The HURDAT2 tropical cyclone climatology database and the multi-source weighted set precipitation (MSWEP) v2 data with a spatial resolution of 0.1 ° x 0.1 ° were used. A total of 92 TCs within a 500-km radius of Puerto Rico were identified for the study period. Contrary to what was expected, a similar percentage of affectation was found between those TCs formed under El Niño (17.39 %) and La Niña (17.39 %) conditions. Regarding the North Atlantic Oscillation, a 23.91 % of the 92 TCs that affected Puerto Rico formed under the negative phase, while the 13.04 % during the positive phase, which is explained in agreement with previous findings with the weakening and shift to the south and west of the Azores High during the negative phase of NAO. The role of the Sea Surface Temperature on the genesis of TCs that affected Puerto Rico was also assessed through the Atlantic Meridional Mode (AMM) and the Atlantic Warm Pool area. In the positive (negative) phase of the AMM was formed the 23.91 % (3.26 %) of the total number of TCs, while under larger (smaller) AWP formed the 61.96 % (16.3 %). It confirms that the affectation of TCs in Puerto Rico is highly related to the eastward extension of the AWP and the SST gradient in the tropical North Atlantic region. Indeed, a westward shift in genesis position was found from July to November. The mean TC rainfall contribution for the cyclonic season was ~ 9 %. It experimented a great interannual variability during the study period and a positive but non-significant trend. As expected, the correlation of the TC rainfall contribution is positively correlated (r = 0.54) with the amount of TCs. Finally, a monthly analysis revealed that in August and September the maximum contribution of rain from CT occurred (~ 17 %), followed by October (~ 6 %) and November (~ 4 %).
sciforum-035241	Analysis of Dry and Wet Episodes in Eastern South America during 1980-2018 Using SPEI Anita Drumond, Milica Stojanovic, Raquel Nieto, Luis Gimeno, Margarida Liberato, Tercio Ambrizzi, Theotonio Pauliquevis, Marina de Oliveira Submitted: 24 Aug 2020 Abstract: Show Abstract	Anita Drumond, Milica Stojanovic, Raquel Nieto, Luis Gimeno, Margarida Liberato, Tercio Ambrizzi, Theotonio Pauliquevis, Marina de Oliveira	N/A		Show Abstract Comment
A large part of the population and the economic activities of South America are located in eastern continent (ESA). ESA is affected by the South American monsoon system, and most of the region belongs to the Amazon, Araguaia-Tocantins, and La Plata basins. The precipitation over ESA may be modulated by the moisture transported from the Atlantic Ocean, mainly the subtropical South Atlantic along the year, and particularly the tropical North portion during the Austral Summer. Extreme climate dry and wet episodes are a recurrent phenomenon in areas of ESA, with environmental and socio-economic impacts, and a quantitative assessment of occurrence of extreme climate events is essential for understanding, monitoring and mitigation of such episodes. This study aims to analyze the extreme climate events at domain-scale occurring over ESA over the last four decades through the multi-scalar Standardized Precipitation-Evapotranspiration Index (SPEI). Based on the results of a Lagrangian approach developed for moisture analysis, the study area consists in the major continental sink of the moisture transported from the Subtropical South Atlantic Ocean towards South America, comprising the Amazonia, almost all the Brazilian territory, and La Plata regions. The SPEI was calculated for the period 1980-2018 using monthly CRU (TS4.03) precipitation and potential evapotranspiration time series (at an original spatial resolution of 0.5 degrees) averaged over the study area. The extreme episodes affecting different components of the hydrological cycle were identified through the SPEI-1, SPEI-3, SPEI-6, and SPEI-12 time series, and their respective indicators (duration, severity, intensity, and peak) were then computed. Preliminary results indicate the predominance of dry episodes in the 2010 decade, while the wet ones prevailed in the middle of the 1990s. The role of the moisture transport from the South Atlantic on the occurrence of these extreme episodes will be investigated in a further study.
sciforum-032851	Analysis of Polarimetric Mini-SAR and Mini-RF Datasets for Surface Characterization and Crater Delineation on Moon Himanshu Kumari, Ashutosh Bhardwaj Submitted: 25 Jun 2020 Abstract: Show Abstract	Himanshu Kumari, Ashutosh Bhardwaj	N/A	N/A	Show Abstract Comment
ISRO's Chandrayaan-1 and NASA's Lunar Reconnaissance Orbiter (LRO) were launched on 22 October 2008 and June 18, 2009, respectively with an aim of exploration along with identification of possible safe sites for future robotic and human lunar missions. These missions have used Miniature Synthetic Aperture Radar (Mini SAR) and Miniature Radio Frequency (Mini-RF) instrument payloads developed by NASA and flown aboard India's Chandrayaan-1 spacecraft and LRO, NASA respectively. These sensors are used for hybrid polarimetry to image shadowed polar regions, where there is a possibility of water to exist. NASA estimates that there are chances of over 600 million metric tons of water ice on the moon, which further prompts the interest of researchers in exploring the moon. The hybrid polarimetric architecture of mini-SAR supports the calculation of Stokes parameters of the backscattered signal, which further allows the derivation of decomposition parameters required to obtain the sub-surface information of the craters. This research aims to study the surface properties of polar and non-polar regions of the Moon and find an approach to detect the boundaries of the Lunar craters. The ArcGIS add-in crater tool was used for delineating the boundaries of the lunar craters using the openly accessible digital elevation model (DEM) generated from Terrain Mapping Camera (TMC) data. The polar craters Nobile, Haworth, Gioja, and an unnamed crater near Byrd along with non-polar craters named Arago and Moltke were investigated for surface characteristics. The Eigenvalues and Eigenvectors were estimated to calculate entropy (H) and the Poincare ellipticity (α) which were used to characterize the scattering mechanism. The three polarimetric decomposition techniques m-δ, m-χ, and H-α applied along with the circular polarization ratio (CPR) were used to obtain the sub-surface information, and identify the shreds of evidence of water ice deposits inside the craters near the polar regions. The results found the dominance of surface scattering inside the craters and double-bounce scattering in the outer region of craters which were graphically analyzed using a transect and box plot. The analytical view of the results proved the hypothesis of the possibility of water ice deposits for the polar craters with the use of decomposition techniques with CPR greater than 1, which further needs validation through other techniques, such as dielectric constant analysis.

Aerosol particles play a central role in the composition and radiation budget of the atmosphere. The aerosol distribution on global and regional scales is dependent on emission, chemical processing, removal and horizontal–vertical transport, and may significantly affect the local and regional air quality. A variety of measurement techniques and numerical modeling tools is used to study the aerosol spatial distribution and its effects on atmospheric composition and radiative transfer. The latter take place through a number of processes, from direct scattering and absorption of solar and planetary radiation to indirect effects related to the formation of cloud droplets and ice particles in the troposphere, or even in the stratospheric polar vortices. Other effects may play a substantial role in the atmospheric radiative transfer, for example, the aerosol deposition feedback on the albedo of snow/ice covered surfaces or the influence on atmospheric stability due to the absorption of radiation. A reliable estimate of the direct radiative effects can be reached if a good knowledge of the vertical distribution of the particles is reached, along with their size distribution and physical composition. A meaningful representation of the indirect effects needs to take several complex microphysical processes into account. Atmospheric aerosols may also cause a negative impact on human health and vegetation. Specific details on emission and chemical mechanisms concerning toxic particulate-borne species are required for an accurate assessment of exposure.

S2. Air Quality

Air quality has become one of the greatest environmental issues of modern times, following improved access to fresh water in many parts of the world. Each year, both outdoor and indoor air pollution are thought to contribute to millions of premature deaths worldwide. Despite increased awareness of the hazards associated with air pollution, there remain significant gaps in our understanding of the science of air quality. Future research will lead to a better understanding of the sources of key atmospheric pollutants, including precursors and the chemistry that leads to production of atmospheric toxins. Improvements are needed in our understanding of the epidemiology of air quality and our understanding is also limited by a lack of comprehensive atmospheric composition measurements in the heterogeneous urban air-shed. Advances in air quality modelling techniques are also needed, as is an understanding of how to bridge the scales between atmospheric models and atmospheric observations. This section aims to publish research that contributes to a better understanding of all these aspects of air quality.

Keywords

Sources of atmospheric pollutants;
Hazardous and toxic substances;
Air quality modelling;

S3. Air Quality and Human Health

The association between air quality and human health is one of the most controversial topics in current research. Air pollution is considered one of the leading environmental risk factor for human health globally, especially with regard to ambient fine particular matter (PM2.5), ozone, and some non-criteria pollutants that are considered to have the highest toxicity, such as metals, organics, ultrafine particles, and black carbon. The interplay between these variables and human health is a popular choice of study. Indirect health impacts also exist, for example, due to changes in vector-borne disease risk, food availability, and agricultural production. Both epidemiology and toxicity mechanism studies are needed to understand the role of air quality on specific health outcomes, including inflammation, DNA changes, cancer, respiratory and neurological diseases, severe cognitive deficit, and brain structural change. Notably, scientifically sound metrics to quantitatively measure atmosphere effects on human health, potentially causing several million deaths per year, are still missing. Therefore, it is necessary to develop significant scientific evidence to guide the development of new recommendations, policies, and legislation.

Articles that consider all associations between atmospheric composition and health impacts, especially with regard to air pollution and aerosols, aerobiology, toxicology, and epidemiology in all regions of the world, are welcome. We also welcome multidisciplinary studies that attempt to use the contextualization of science to solve this broad societal challenge.

S6. Biometeorology

Biometeorology deals with the interactions between atmospheric conditions and living organisms (humans, vegetation and animals) in an interdisciplinary manner, as well as on how to inform, warn, respond to and mitigate adverse effects resulting from activities and climate change. The core questions are to assess how atmospheric conditions can impact on living organisms. The topic covers aspects from daily life to implications of global, regional and local climate change.

Examples are how the well-being and health of humans are related, how urban planning can improve atmospheric conditions (air quality, urban climate), atmospheric effects on agricultural and forest production and how to transfer such knowledge in a broadly understandable way in order to ensure the appropriate usage of such information. Atmospheric conditions include transient ones driven by weather patterns and long-term climatology, as well as how climate change trends may affect these drivers. In this context, the section wants to address issues concerning assessment approaches (incl. emission inventories) for urban climate (incl. heat load and cold stress), air quality and health, as well as warning systems and measures in place to mitigate adverse impacts. Modelling and experimental studies on how environmental management, urban planning and design or traffic regulation can improve living conditions and decrease emissions are particularly welcome. Articles considering the impacts of weather processes with respect to air temperature, air quality and radiation on human well-being and health would also be appropriate. Since several methods are in use to compile bio-weather and air quality forecasts, we are looking forward to discussing such approaches and the way to convey such information to end-users and the public, but particularly to special target cohorts. Another aim is to describe not only how climate and air quality data and information should be transferred and addressed for issues on tourism and recreation, but also for people living in urban areas.

Urban bioclimatology;
Climate, tourism and recreation;
Thermal comfort and heat stress;
UV-radiation;
Weather sensitivity;
Biometeorology and climate change;
Agricultural meteorology;
Forest meteorology;

S8. Biosphere/Hydrosphere/Land–Atmosphere Interactions

Biosphere/Hydrosphere/Land–Atmosphere interactions play a crucial role in weather and climate. Surface water and energy exchange fluxes drive the diurnal and seasonal dynamics of the atmospheric boundary layer, on both local and regional scales. Surface–atmosphere trace gas exchange fluxes affect the chemical composition of the boundary layer, acting both as a source and a sink of atmospheric trace species, including both greenhouse gases and more reactive species that drive atmospheric chemistry, such as isoprene. Together, these surface–atmosphere interactions thus dominate the environmental conditions of life on Earth. As man-made emissions are altering the Earth’s energy budget, surface–atmosphere interactions are changing as well. Magnified or reduced hydrologic cycles and slowly changing biosphere and land surface conditions owing to land use change or increasing frequency of extreme weather and climate occurrences, will not only alter local to regional energy and water fluxes, but also trace gas exchange rates. Both are expected to create feedbacks on atmospheric conditions, including atmospheric chemistry, which will need to be understood to project future risks, and to effectively respond with mitigation and adaptation strategies.

Atmosphere invites contributions analyzing how local to regional energy and trace gas exchanges between the surface and the atmosphere affect atmospheric conditions, including, but no limited to, weather and climate phenomena from local to regional scales, exchange mechanisms, greenhouse gas and other trace gas fluxes and their atmospheric reactions, deposition processes, or anthropogenic land use change effects.

Keywords:

Atmospheric boundary layer;
Surface–atmospheric interactions;
Land–atmospheric interactions;
Forests–atmosphere interactions;
Air–sea interactions;
Wind–wave interactions.

S9. Upper Atmosphere

The problem of coupling processes in the Earth's atmosphere has recently become of great relevance. Climate change, electric discharges from top of the clouds into the ionosphere, seismo-ionospheric coupling, the role of galactic cosmic rays in cloud formation and hurricane stimulation, and other novel issues present the challenge of reconsidering the energy balance and transformation within the upper atmosphere. Usually, the lower border of the upper atmosphere is positioned at altitudes higher than 50 km, where the processes of molecule dissociation and ionization start to play an important role. This altitude is also considered as the lower border of the ionosphere in models of global electric circuits. However, for this Section, our interest lies in the lower atmosphere up to the tropopause, where the maximum dissipation of galactic cosmic rays is situated, as well as a few kilometers higher than the tropopause, where we focus attention on the ozone layer and its role in atmosphere thermodynamics.

We envisage that this Section will represent the efforts of scientists who are not only atmospheric physicists but also experts in plasma physics, thermodynamics, and other disciplines of geophysics. The new knowledge generated from this endeavor is the direct result of interdisciplinary fusion and sets the foundation for further scientific progress.

S10. Planetary Atmospheres

The Planetary Atmospheres section broadly includes studies involving the atmospheres of solar-system planets and moons (with Earth included in comparative planetology studies), and the atmospheres of extrasolar planets. For solid-surface (terrestrial) planets, the regional scope spans from the planetary boundary layer to the thermosphere. For gas–giant planets, the regional scope spans from interaction with the deep fluid interior to the thermosphere. Space weather is generally treated elsewhere, but the interaction with aeronomy is in the section's scope.

All types of studies are welcome, including observations and data analysis, modeling, model expositions, theoretical work, laboratory studies, and remote sensing and in situ probe feasibility studies. A full range of topics is covered, including atmospheric dynamics, atmospheric chemistry, atmospheric structure, formation and evolution, observation strategies, and the interplay between disciplines. Comparative planetology is particularly encouraged.
