- An advanced carbon dioxide retrieval algorithm for satellite observations has been developed at the Institute of Atmospheric Physics, Chinese Academy of Sciences. The algorithm is tested using Greenhouse gases Observing SATellite (GOSAT) L1B data and validated using the Total Column Carbon Observing Network (TCCON) measurements. The retrieved XCO2 agrees well with TCCON measurements in a low bias of 0.15ppmv and RMSE of 1.48ppmv, and captured the seasonal variation and increasing of XCO2 in Northern and Southern Hemisphere, respectively, as other measurements.
