Pollution : CO2 patches has been clearly dissipated quite a bit but incase of NO2 the hotspot patches remain the same but the radius of density got a decrease in concentration. It is partially because of the scaling difference between CO2 - NO2 and also NO2 is mainly emitted by thermal power plants, which was not shutdown due to lockdown, they functioned during this period. So there's an inference here. Also In NO2 emission monthly time series graph we can see that the emission drops in the months of June ,July ,August and increases from there on. It may be due to the monsoon winds which provide sources for wind and hydro power generation.
