Abstract

The joint methane vertical profile retrieval from the thermal infrared (TIR) and shortwave infrared (SWIR) satellite spectra allows to improve the vertical resolution of the spectral data processing method. However, spectrometers with a dense spatial coverage such as IASI/METOP or AIRS/AQUA have only TIR spectrometers, which provide maximum sensitivity for methane content in the middle troposphere. On the other hand, TANSO-FTS/GOSAT is unique spectrometer with both ranges, but it has a rare spatial coverage. The paper describes the technology of using TANSOFTS measurements to constrain the inverse problem solution for vertical methane profile retrieval from multiple IASI spectra (1220-1310 cm^-1 ) in the vicinity of a single TANSO-FTS measurement using the 5937-6110 cm^-1 range.
