Atmospheric Chemistry and Physics (ACP) is a not-for-profit international scientific journal dedicated to the publication and public discussion of high-quality studies investigating the Earth's atmosphere and the underlying chemical and physical processes. It covers the altitude range from the land and ocean surface up to the turbopause, including the troposphere, stratosphere, and mesosphere.

The main subject areas comprise atmospheric modelling, field measurements, remote sensing, and laboratory studies of gases, aerosols, clouds and precipitation, isotopes, radiation, dynamics, biosphere interactions, and hydrosphere interactions (for details see journal subject areas). The journal scope is focused on studies with general implications for atmospheric science rather than investigations that are primarily of local or technical interest.

Dear colleagues, due to the current coronavirus situation, we are experiencing unusual challenges and delays in manuscript handling and reviewing, for which we would like to ask for your understanding.

Many thanks and best wishes, the ACP executive editors on behalf of the editorial board

21 Sep 2021 The role of emission reductions and the meteorological situation for air quality improvements during the COVID-19 lockdown period in central Europe

COVID-19 lockdown measures in spring 2020 led to cleaner air in central Europe. Densely populated areas benefitted mainly from largely reduced NO2 concentrations, while rural areas experienced lower reductions in NO2 but also lower ozone concentrations. Very low particulate matter (PM) concentrations in parts of Europe were not an effect of lockdown measures. Model simulations show that modified weather conditions are more significant for ozone and PM than severe traffic emission reductions.

30 Jul 2021 New ACP Letter: Better representation of dust can improve climate models with too weak an African monsoon

Earth system models have a few persistent biases that impinge on our ability to make robust future regional predictions of precipitation. For the last fifteen years, there has been little to no improvement in these biases. This work presents an accurate representation of how dust absorbs radiation based upon its observed mineralogical composition and size distribution.

27 Jul 2021 Secondary organic aerosols from anthropogenic volatile organic compounds contribute substantially to air pollution mortality

Secondary organic aerosol (SOA) is an important aspect of poor air quality for urban regions around the world, where a large fraction of the population lives. However, there is still large uncertainty in predicting SOA in urban regions.
