Special Issue Information

Dear Colleagues,

Increases of ozone-depleting substances (ODSs) in the atmosphere have led to stratospheric ozone depletion and the ozone ‘hole’. Actions prompted by the Montreal Protocol have resulted in decreasing ODSs and have helped to avoid large increases of solar ultraviolet (UV-B) radiation. Besides, continued emissions of greenhouse gases (GHGs) will change the climate and modify the recovery of stratospheric ozone. Climate change will also affect clouds, surface reflectivity at high latitudes, where changes in sea ice and snow cover are expected, and aerosols near the Earth’s surface. The combined effects of changes in ozone, aerosols, clouds, and reflectivity will determine future levels of UV-B radiation at the Earth’s surface. In many cases, there is a growing influence from changes in seasonality and extreme events due to climate change.

This special issue focuses on findings of current and projected interactive environmental effects of stratospheric ozone depletion, solar UV radiation, and climate change. These effects include those on atmosphere and air quality, human health, terrestrial and aquatic ecosystems, biogeochemical cycles, solar energy technologies, and materials used in construction and other services. We also focus on the assessment of the resulting changes in stratospheric ozone, UV radiation and climate, regarding the effects on humans and the environment, including recent unexpected events, such as the COVID-19 pandemic and unprecedented increases in UV radiation over the Arctic in 2020 due to stratospheric ozone depletion.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Atmosphere is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

In this research, a new time-resolved emission inversion system was developed to investigate variations in SO2 emission in China during the COVID-19 (Corona Virus Disease 2019) lockdown period based on a four-dimensional variational (4DVar) inversion method to dynamically optimize the SO2 inventory by assimilating the ground-based hourly observation data. The inversion results obtained were validated in the North China Plain (NCP). Two sets of experiments were carried out based on the original and optimized inventories during the pre-lockdown and lockdown period to quantify the SO2 emission variations and the corresponding prediction improvement. The SO2 emission changes due to the lockdown in the NCP were quantified by the differences in the averaged optimized inventories between the pre-lockdown and lockdown period. As a response to the lockdown control, the SO2 emissions were reduced by 20.1% on average in the NCP, with ratios of 20.7% in Beijing, 20.2% in Tianjin, 26.1% in Hebei, 18.3% in Shanxi, 19.1% in Shandong, and 25.9% in Henan, respectively. These were mainly attributed to the changes caused by the heavy industry lockdown in these areas. Compared to the model performance based on the original inventory, the optimized daily SO2 emission inventory significantly improved the model SO2 predictions during the lockdown period, with the correlation coefficient (R) value increasing from 0.28 to 0.79 and the root-mean-square error (RMSE) being reduced by more than 30%. Correspondingly, the performance of PM2.5 was slightly improved, with R-value increasing from 0.67 to 0.74 and the RMSE being reduced by 8% in the meantime. These statistics indicate the good optimization ability of the time-resolved emission inversion system. Full article
