IASI Level 1 - 500 Selected Channels and Principal Component Scores - Metop - Regional
Description
The IASI principal component scores product contains IASI radiance spectra (see the IASI GDS L1C), compressed by the Principal Component Analysis method. Calibrated and geolocated IASI observations in a combined product containing both 300 Principal Component Scores and 500 original IASI Channels, cloud/scene analysis information, BUFR formatted. 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 EUMETSAT Advanced Retransmission Service (EARS) provides instrument data from the Metop satellites collected via a network of Direct Readout stations.
NOTE: Since 15/10/2021, Metop-A EARS regional data are no longer available.
