ESA SEOM-IAS – Spectroscopic parameters database 2.3 µm region

The database contains molecular absorption line parameters obtained within the framework of the esa project SEOM-IAS (Scientific Exploitation of Operational Missions - Improved Atmospheric Spectroscopy Databases), ESA/AO/1-7566/13/I-BG. Details on the project can be found at http://www.wdc.dlr.de/seom-ias/.

FTS and CRDS measurements (performed at the German Aersopace Center (DLR) and at Université Grenoble Alpes) were analyzed in the spectral range 4190-4340 cm^-1 within the framework of the esa project SEOM-IAS resulting in an improved line parameter database of H₂O, CH₄ and CO absorption lines according to the needs of the TROPOMI instrument aboard the Sentinel 5-P satellite. The parameters are compiled in three ASCII files, one for each molecule (CH4_sigma_S_air_broadening_Tdep_May17_V3.hit, H2O_May17_V3.hit, CO_Sep16.hit).
