ESA SEOM-IAS – Spectroscopic parameters database 2.3 µm region

  • 1. German Aerospace Center (DLR)
  • 2. Laboratoire Interdisciplinaire de Physique (LIPhy), Université Grenoble Alpes


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

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).
