IASI Level 1C Climate Data Record Release 1 - Metop-A

Abstract:
The main objective of the Infrared Atmospheric Sounding Interferometer (IASI) is to provide high-resolution atmospheric emission spectra to derive temperature and humidity profiles with high spectral and vertical resolution and accuracy. Additionally it is used for the determination of trace gases such as ozone, nitrous oxide, carbon dioxide and methane, as well as land and sea surface temperature, emissivity and cloud properties. The IASI L1c product contains infrared radiance spectra at 0.25cm-1 resolution. The product has for each sounded pixel 8461 spectral samples covering the range between 645.0 cm-1 and 2760 cm-1 wavenumbers. This is the Metop-A IASI level 1c Release 1 data record. This was reprocessed using the version 7.4.0 of the operational software and used IASI Level 0 data plus the last updated auxiliary files provided by CNES. This release comprises level 1c data from Metop-A satellite for the period ranging from the 10th of July 2007 until the 31st of December 2017. This is a Fundamental Climate Data Record (FCDR)., i.e., a long-term data record of calibrated and quality-controlled sensor data designed to allow the generation of homogeneous products that are accurate and stable enough for climate monitoring and data assimilation for re-analysis of the recent climate.
