IASI Level 1 Principal Component Scores - Metop - Global
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 principal component scores product contains IASI radiance spectra (see the IASI GDS L1C), compressed by the Principal Component Analysis method. Each of the IASI spectra is represented by a small number of coefficients (scores). The reconstruction of noise-reduced spectra from the scores uses three sets of eigenvectors, referenced in the product and available from EUMETSAT.
NOTE: From 15/10/2021, Metop-A IASI data are no longer available.
