I got tired of always doing the same NO2 maps/animations, so here is something a bit different. India's lockdown caused a drop in NO2 concentrations in cities (about -50%), while coal-fired power plants remain the most polluted spots.

Annotating satellite images is so underrated, it can be very time consuming, but those small details are adding so much information and value to the image!. This is an example of rock-ice avalanches in the Himalayas observed with Sentinel-2.
