IASI Surface Emissivity - Metop

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 Surface Emissivity product contains surface emissivity at twelve wavelengths, derived from the IASI sounder measurements (of IASI L1C product). The full emissivity spectrum can be inferred in all IASI channels from these 12 wavelengths as explained in the IASI L2 Product Guide listed in the Online Resources. The products are provided at the single IASI footprint resolution (which is about 12 km with a spatial sampling of about 25 km at Nadir). The quality of the emissivity product is strongly related to the cloud properties available in the IASI CLP product. This product is available via the Data Centre as the IASI Combined Sounding Products: EO:EUM:DAT:METOP:IASSND02.
