Dashed: the projection from the latest reading. A projection, not a promise.
Contains modified Copernicus Sentinel data, processed by KNMI (TEMIS). Monthly mean tropospheric NO2 from TROPOMI on Sentinel-5P, averaged by Palanor over Natural Earth boundaries. NO2 is far higher in winter than in summer.
China's industrial heartland seen from space: steel, coal power, chemicals and heavy traffic. Each winter peak shows how much fuel the region burned that season.
