In this study, NO2 tropospheric column amounts were obtained from the NASA website (https://so2.gsfc.nasa.gov/no2/no2_index.html). The NO2 maps over SEA were produced using high resolution daily gridded at 0.1° × 0.1° spatial resolution, which is then averaged over a 15-day window (Krotkov et al., 2017; Lamsal et al., 2020). We used maps that represent 1 March, 31 March, and 17 April (the latest available data at the time of writing the original manuscript). We also used NO2 data averaged over 2015–2019 (baseline), in order to detect the absolute differences between 2020 and the baseline data (Krotkov et al., 2017; Lamsal et al., 2020). We did not use the NO2 data from TROPOMI because data prior to 2020 is limited.

NO2 concentrations should be read as NO2 tropospheric column amounts.
