VIRTUAL | Air Quality and Climate Impacts of COVID-19 Lockdowns

DATE

LOCATION

Virtual Meeting

This was a joint meeting with the Atmospheric Chemistry Special Interest Group.
The COVID-19 pandemic has had a profound impact on lives and livelihoods worldwide. From an atmospheric chemistry perspective, government stay-at-home policies (“lockdowns”) to control the virus spread led to significant reductions in the emission of various air pollutants and short-lived climate forcers. A large number of studies have utilised surface observations, satellite data and models to report the observed changes in atmospheric composition in response to these measures. However, in addition to emissions, ambient concentrations of key air pollutants (e.g. NOx, O3) are determined by a range of factors which can exhibit large spatial and temporal variability (e.g. meteorology). This confounds assessment of how lockdown-induced emission changes translate into air quality improvements. In this meeting, we will discuss this and other important aspects of COVID-19 responses on atmospheric chemistry and climate.

Meeting Chairs: Ryan Hossaini and Paul Griffiths
