ECAS 2020 has been a success! Welcome to the new electronic conference EACS 2023.
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-035241 | Analysis of Dry and Wet Episodes in Eastern South America during 1980-2018 Using SPEI | , , , , , , , | N/A |
![]() |
Show Abstract |
||||||||||||||||||||||||||||||||||||
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. |

Show Abstract |
||||||||||||||||||||||||||||||||||||
Representation of atmospheric boundary layer (ABL) over sea ice is a challenge for numerical weather prediction (NWP) models. Particularly, when it comes to stable or near neutral ABL, where models tend to erroneously simulate 2-m temperature, 10 m wind speed and other variables strongly affected by atmosphere-surface coupling. Studies indicate that submesoscale processes, not resolved directly by the models, might be responsible for those inaccuracies. Development of new parameterizations that would improve models performance is hampered by the limited amount of field data from the sea ice covered areas. To increase our knowledge about relevant processes a Hailuoto Atmospheric Observations over Sea Ice (HAOS) campaign was carried out over the sea ice in the Bothnian Bay (Baltic Sea) on 27 February - 2 March 2020. Observations included 27 Unmanned Aerial Vehicles (UAV) flights collecting meteorological data (temperature, wind speed, air pressure) and 4 photogrammetry missions over a stretch of sea ice, along with continuous, shore based automatic weather station (AWS) and LIDAR wind measurements. Obtained dataset is used for the validation of several mesoscale models results including WRF, run operationally by the Interdisciplinary Centre for Mathematical and Computational Modelling at University of Warsaw, AROME-ARCTIC run by Norwegian Meteorological Institute and HIRLAM from Finnish Meteorological Institute. Furthermore, the WRF Single Column Model (SCM) is launched multiple times for the comparison of different planetary boundary layer (PBL) and microphysics schemes influence on the model capability to reproduce the observed conditions. Considering that throughout the campaign the weather was dominated by low winds, clear skies and low temperatures, our research provides a valuable insight into the model strengths and shortcomings in the numerical modeling of stable boundary layer, together with the evaluation of alternative ABL parameterizations. |

Show Abstract |
||||||||||||||||||||||||||||||||||||
The variability in the intensity and frequency of extreme hydrometeorological events due to climate change have an enormous impact in managing water resources in developing countries. Frequently it has been recognized sudden droughts and a severe floods. This study analyzed the spatial and temporal trends of five meteorology indices: annual maximum precipitation (AMP),annual precipitation (AP), mean areal precipitation (MAP),annual maximum temperature (AMaT) and annual minimum temperature (AMiT) and three stream flow indices: mean annual flow(MAF), annual maximum flow (AMaxF) and total mean annual flow (TMAF) over the Tendaho Catchment. Mann-Kendall (MK), Spearman Rho (SR), Sen’s slope test in R-program modifiedmk package and Sen innovative trend test were used to detect trends of 16 meteorological and one stream flow stations from 1979-2017. The result showed that there is a statistically significant temporal trends only in AMP, AP, AMaT and AMiT at 6, 19, 56 and 50% of the stations respectively. The remaining indices have no statistically significant trend in all the stations. It also dictates that the catchment is characterized by a slightly increasing AP and AMP; a slightly decreasing MAP and a significant increasing AMaT and AMiT trends. Except AMaT, there is no particular spatial pattern of AP, MAP and AMiT on the majority of the stations. Whereas, all stream flow indices showed a slightly decreasing temporal trend at 95% confidence. From this, we can conclude that the decreasing flow trend could be due to the decrement of MAP, an increment of temperature and construction of reservoirs in the catchment. |

sciforum-034523 | A Preliminary Study of Winter Atmospheric River’s Precipitation Characteristics Using Satellite Data over Galicia (NW Spain) | , , , , , , | N/A | N/A |
Show Abstract |
||||||||||||||||||||||||||||||||||||
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-035003 | The Interannual and Interdecadal Variability of Soil Moisture and Recent Tornado Activity (F2 or Greater) in the Central USA | , , | N/A |
![]() |
Show Abstract |
||||||||||||||||||||||||||||||||||||
Previous studies have demonstrated that El Nino and Southern Oscillation (ENSO) have a distinct impact on the occurrence of severe weather and the attendant environment in the eastern two thirds of the USA. Typically, La Nina years have been shown to be more active in the central USA. Here, a previous study of tornado activity in Missouri from 1948 – 1999, as well as the neighboring states of Iowa, Nebraska, and Kansas, is updated to included the most recent two decades. The datasets used in this study were the National Centers for Environmental Prediction / National Center for Atmospheric Research (NCEP / NCAR) re-analyses and the National Oceanic and Atmospheric Administration (NOAA) Storm Prediction Center (SPC) event archive were used. The results demonstrated that recently tornado activity in this region was higher than that of the late 20th century suggesting interdecadal variability in the time series. The interannual variability for the latest two decades is similar to that of the last half of the 20th century. Finally, these results will show that there is a correlation between the in-season soil moisture and tornado activity, but it is not clear whether the correlation was a lead or lag |

S1. Aerosols
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.

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

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.
