| Abstract: | The 1st Chinese carbon dioxide(CO_2) monitoring satellite mission, TanSat, was launched in 2016. The 1st TanSat global map of CO_2 dry-air mixing ratio(XCO_2) measurements over land was released as version 1 data product with an accuracy of 2.11 ppmv(parts per million by volume). In this paper, we introduce a new(version 2) TanSat global XCO_2 product that is approached by the Institute of Atmospheric Physics Carbon dioxide retrieval Algorithm for Satellite remote sensing(IAPCAS), and the European Space Agency(ESA) Climate Change Initiative plus(CCI+) TanSat XCO_2 product by University of Leicester Full Physics(UoL-FP) retrieval algorithm. The correction of the measurement spectrum improves the accuracy(-0.08 ppmv) and precision(1.47 ppmv) of the new retrieval, which provides opportunity for further application in global carbon flux studies in the future. Inter-comparison between the two retrievals indicates a good agreement, with a standard deviation of 1.28 ppmv and a bias of -0.35 ppmv. |
