IASI Atmospheric Temperature Water Vapour and Surface Skin Temperature - 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, as well as land and sea surface temperature, emissivity and cloud properties. The Atmospheric Temperature, Water Vapour and Surface Skin Temperature ( TWT) product contains the vertical profiles of atmospheric temperature and humidity, with a vertical sampling at 101 pressure levels, and surface skin temperature. The vertical profiles are retrieved from the IASI sounder measurements (of IASI L1C product) together with collocated microwave measurements (AMSU & MHS 1B) when available. 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 and yield of the vertical profiles retrieved in cloudy IFOVs is strongly related to the cloud properties available in the IASI CLP product and the availability of collocated microwave measurements. This product is available via the Data Centre as the IASI Combined Sounding Products: EO:EUM:DAT:METOP:IASSND02 NOTE: From 15/10/2021, Metop-A IASI data are no longer available.
