The coronavirus-19 (COVID-19) pandemic led to government interventions to limit the spread of the disease that are unprecedented in the last decades. Stay at home orders and other measures led to sudden decreases in emissions, most visibly from the transportation sector. In this database, the current knowledge and understanding of the influence of these emission reductions on atmospheric composition and notably air quality are summarized with a focus on short-lived species.
This data collection builds on the paper "The global impacts of COVID-19 lockdowns on urban air quality: a review and recommendations" that covers literature up to September 30th 2020.
We invite authors of relevant papers to upload their data to the collection, expanding the database in time, space, and compounds covered. Data from remote and ground-based measurements as well as modelling studies and emission inventories are welcome.
Last database update: 2023-01-26 (version 5) adding 64 new publications with 930 new measurements.
