Quantifying COVID-19 enforced global changes in atmospheric pollutants using cloud computing based remote sensing

This dataset contains the percentage change in PM2.5, NO2, Tropospheric ozone, and AOD over 93 major megacities of the world using cloud computing enabled satellite data-based remote sensing. NO2 and Tropospheric ozone are used using Google Earth Engine from Sentinel-5P, AOD from MODIS and PM2.5 is the data-assimilated product from ECMWF.
