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-041713 | First Conclusions from the WMO/GAW Coordinated Study on Impacts of COVID-19 Lockdown Measures on Air Quality: An Observational and Modelling Analysis |
![]() |

Show Abstract |
|||||||||||||||||||||||||||||||||||||
The aim of this World Meteorological Organisations’ Global Atmospheric Watch (WMO/GAW) programme coordinated study is to understand how air quality has changed in cities across the globe as a result of measures to control the spread of the COVID-19 virus. The observational analysis reported here focusses on changes in PM2.5, PM10, NO2 and O3 concentrations during the 2020 lockdown periods in more than forty cities compared to the mean of previous five year (2015-2019) for the same periods. Similarly, a range of meteorological parameters have also been compared to assess how the meteorology may be different between the 2020 and the previous five years. All observational data has been supplied by local teams who were responsible for the QA/QC checks. A new phase of modelling analysis has also been initiated and we report here on one case study for the changes in air pollution over the UK. For the modelling analysis, a baseline (BL) was defined to represents the UK and Europe emissions assuming no lockdown measures between 1 March to 26 April 2020 (with lockdown beginning on 24 March). Scenario 1 (S1) is defined as a plausible scenario to represents the overall comprehensive changes in emissions in the key sectors over the lockdown period of 24 March to 26 April. A second scenario (S2) represents a sensitivity scenario to estimate the changes in air quality species attributable to reductions only in road traffic emissions over the lockdown period of 24 March to 26 April. The modelling analysis has been conducted with WRF/CMAQ modelling system with a spatial grid resolution of 10x10km over the UK domain. Observational analysis of over forty cities shows a reduction up to 60% in NO2 and up to 40% in PM2.5 but with regional differences. For example, air pollution concentrations in some cities shows an increase in PM2.5 which was attributed to mainly long range transport. A comparison with WHO Guidelines shows that for most cities, the NO2 decrease during the lockdown periods leads to meeting the annual guideline value. For PM2.5, the improvements are smaller and concentrations remain above guidelines for many regions, especially China, India, S Korea, Latin America. The observational results are corroborated by the modelling analysis conducted for the UK. Model predictions for S1 reveal a reduction in NO2 of about 30-40% in urban and 20-40% in rural areas. In the case of PM10 and PM2.5 model predicts about 20% reductions in urban locations and about 15% in rural areas. The reduction in PM10 is in part due to the reduction in the coarse fraction (PM10 – PM2.5) of up to 14% in urban areas. There are some small increases predicted in O3 concentrations near airports and urban areas, where levels of nitrogen dioxide are significantly reduced. Analysis of S2 shows that most of the changes during the lockdown period can be attributed to reduction in road traffic emissions. The study is currently being extended to (i) link changes in air pollutant concentrations to emissions changes, (ii) identifying regional differences across the globe and (iii) identifying lessons learnt for transitioning to lower air pollution emissions and improve air quality in global cities. Note: no results of this study can be circulated or reported without the express opinion of Professor Ranjeet S Sokhi, Chair of WMO/GAW GURME. |

sciforum-035219 | Long-term changes in solar shortwave irradiance due to different atmospheric factors according to measurements and reconstruction model in Northern Eurasia | , | N/A |
![]() |
Show Abstract |
||||||||||||||||||||||||||||||||||||
The temporal variability of solar shortwave radiation (SSR) was assessed over Northern Eurasia (40o – 80o N; 10o W – 180o E) by using SSR reconstruction model since the middle of 20 century. The reconstruction model estimates the year-to-year SSR variability as a sum of variations in SSR due to changes in aerosol, effective cloud amount and cloud optical thickness which are the most effective factors affecting SSR. The retrievals of year-to-year SSR variations according to different factors were tested against long-term measurements in Moscow State University Meteorological Observatory during 1968-2016. The reconstructed changes show a good agreement with measurements with determination factor R2 = 0,8. The analysis of SSR trends since 1979 has detected a significant growth of 2.5% per decade, which may be explained by its increase due to change in cloud amount (+2.4% per decade) and aerosol optical thickness (+0.4% per decade). The trend due to cloud optical thickness was statistically insignificant. Using the SSR reconstruction model we obtained the long-term SSR variability due to different factors for the territory of Northern Eurasia. The increasing SSR trends have been detected on most sites since 1979. The long-term SSR variability over Northern Eurasia is effectively explained by changes in cloud amount and, in addition, by changes in aerosol loading over the polluted regions. The retrievals of the SSR variations showed a good agreement with the changes in global radiance measurements from World Radiation Data Centre (WRDC) archive. The work was supported by RFBR grant number 18-05-00700. |

sciforum-041351 | Multifractal detrended fluctuation analysis of relative humidity over Greece | , , | N/A | N/A |
Show Abstract |
||||||||||||||||||||||||||||||||||||
Water, in its various forms, is considered a key parameter in climate change studies. Water vapor is recognized as the most important natural greenhouse gas playing a vital role in the hydrological cycle. Thus, studying air humidity fluctuations may contribute towards a deeper understanding of the radiative and thermodynamic processes that take part in the Earth’s atmosphere. Traditional statistical analysis is not always efficient to describe complex physical processes with high temporal variability. In addition, a more thorough study of the variations of climatic parameters requires examination of their time series fluctuations over multiple time scales. Fractal theory offers robust solutions that satisfy the above requirements. In this work, the Multifractal Detrended Fluctuation Analysis (MF-DFA) is used in order to investigate the intrinsic dynamics of daily relative humidity time series over the Greek region from a nonlinear perspective. The scaling properties and the multifractal structure of the time series are studied by examining the fluctuation function, the multifractal spectrum and the Hurst exponent. |

sciforum-032494 | Effect on the Air Quality and Noise Levels of Jaipur City in the Event of COVID-19: A Short Review | N/A | N/A |
Show Abstract |
|||||||||||||||||||||||||||||||||||||
Jaipur has seen a rapid development in the last two and a half decades being the capital city of Rajasthan and its proximity to the National capital region of India, directly impacting its environment. This systematic review and meta-analysis aimed to evaluate the status of air pollution based on available literature. A review based on status of air pollution beginning with works of researchers in 1996-97 period for Jaipur city, till the recent developments through published literature is presented here in the light of abrupt and extreme situations arising due to COVID-19. High Volume Samplers having respirable dust sampler with dust collector and filter paper were utilized in these studies and it was conducted by dividing the city into various categories such as: industrial area, commercial area, residential area, and sensitive area. Sulphur dioxide and nitrogen dioxide were measured by doing gas sampling and passing the gas through absorbing solution of sodium tetrachloromercurate and sodium hydroxide – sodium arsenite solution respectively. Carbon monoxide monitors of type CO-200 were being used to detect presence of CO and indicate the concentration in ppm. Researchers have found that the recorded mean values of PM2.5 and PM10 were much higher than the specified limit by National Ambient Air Quality Standards (NAAQS). Sound level meters were used for the measurement of noise levels. Currently, daily AQI results are provided through online services based on PM2.5, PM10, NO2, NH3, SO2, CO and ozone. The AQI on 15th May 2020 is 92, 98, and 100 at 9:00 AM, 11:00 AM, and 2:00 PM representing satisfactory category. However, AQI was 102 (moderate) at 3:00 PM and 4:00 PM. Jaipur is witnessing a major improvement in the air quality index (AQI) and noise levels during the COVID-19 crisis period due to limited anthropogenic activity since mid-March 2020. |

sciforum-035093 | Long-Term Cloud Cover Variations within the Region of Optical Observatories in the South of Eastern Siberia | N/A | N/A |
Show Abstract |
|||||||||||||||||||||||||||||||||||||
In the south of Eastern Siberia (Russia), there are three optical observatories of the Institute of Solar-Terrestrial Physics of the Siberian Branch of the Russian Academy of Sciences. The observatories are equipped with instruments to observe the Sun, near and deep space. The first one, Sayan Solar Observatory, is located in the mountains at the height of 2,000 m (51.67 N, 100.99 E). The second, Baikal Astrophysical Observatory, is on the southern bank of Lake Baikal near the settlement of Listvyanka (51.86 N, 104.86 E). These two observatories were built in the 60s — 70s of the last century. The third observatory is now being built in settl. Tory, Buryatia (51.78 N, 103.00 E). During space observations in the optical range, atmospheric conditions are of great importance. The purpose of this work is to study the long-term dynamics of cloud cover within the region of the optical observatories. We used the following data: Monthly mean High cloud cover, Low cloud cover, Medium cloud cover and Total cloud cover (TCC) values derived from ERA-Interim 1979–2018 with spatial resolution 1º×1º and Monthly mean TCC values derived from NCEP Reanalysis Gaussian Grid 1948–2019. We calculated cloud cover values averaged along 50,475º N (NCEP) and along 51º N (ERA) over 101º–105º E (5 grid points for ERA and 3 grid points for NCEP). We found that since about the mid-1990s, the amount of high, medium, and low cloud cover has been decreasing in summer. While only positive cloud cover anomalies were detected during construction of the observatories and the first observations at them, since 2005, the cloud cover anomalies are predominantly negative. |

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.

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