Carbon dioxide monitoring satellite TanSat, launched in 2016, has produced its 1st batch of human-caused carbon dioxide emission (CO2) signatures, offering a scientific basis for the country's efforts to combat global warming. The journal Advances in Atmospheric Sciences published a paper which introduces the first attempt to detect anthropogenic CO2 emission signatures using CO2 observations from TanSat and NO2 measurements from the TROPOspheric Monitoring Instrument (TROPOMI) onboard the Copernicus Sentinel-5 Precursor (S5P) satellite. The analysis focusses on 2 selected cases in Tangshan, China and Tokyo, Japan. It was found that the TanSat XCO2 measurements have the capability to capture the anthropogenic variations in the plume and have spatial patterns similar to that of the TROPOMI NO2 observations.
