文摘

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 0.15 ppmv and RMSE of 1.48 ppmv, and captured the seasonal variation and increasing of XCO₂ in Northern and Southern Hemisphere, respectively, as other measurements. Keywords Retrieval algorithm Satellite remote sensing Carbon dioxide Carbon flux GOSAT
