Abstract

The GOSAT-2 satellite was launched in August 2018 to continue the global greenhouse gas monitoring project. Here, using the original FIRE-ARMS software, we performed retrieval of the atmospheric main methane isotopologue dry air mole fraction (XCH₄) from TANSO-FTS/GOSAT-2 satellite Fourier spectrometer spectra in thermal infrared range over the Kanto area, Japan (34.75-36.75N; 139-141E) in February-April 2019. The optimal estimation method was used to solve the inverse problem. The CAMS Near-Real-Time reanalysis data of European Centre for Medium-Range Weather Forecasts was used as an initial guess.
