These maps show nitrogen dioxide (NO2) values across China from 1 January 2020 to 20 January 2020 (before the quarantine) and 10 February 2020 to 25 February 2020 (during the quarantine). The data were collected by the Tropospheric Monitoring Instrument (TROPOMI) on ESA’s Sentinel-5 satellite. A related sensor, the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite, has been making similar measurements. Graphic: Joshua Stevens / NASA Earth Observatory
