TanSat, launched in December 2016 as China's first satellite dedicated to monitoring global carbon dioxide — making China only the third country after Japan and the United States to track greenhouse gases from its own dedicated spacecraft. TanSat measures atmospheric CO2 with enough precision to detect the specific signature of human-caused emissions from individual cities, comparing plumes over Tangshan and Tokyo in later research. A larger successor constellation, TanSat-2, is now in development to monitor emissions city-by-city twice daily.
