05 February 2020
IASI-NG (Infrared Atmospheric Sounder Interferometer — New Generation) has a direct heritage from the IASI instrument on board EUMETSAT Polar System (EPS) satellites. IASI-NG will ensure continuity to EPS Infrared Atmospheric Sounder mission, with improved spectral and radiometric performances.
Test data description
The test data are available here:
The IASI-NG L1D test data set is generated using the IASI-NG L1D IPP (In-house Prototype processor) using L1C test data and auxiliary data as input. The auxiliary data (IAS-1D-AUX_EIGV and IAS_1D_AUX_PCCC) contain the IASI-NG eigenvectors and the static parameters to configure the Principal Component Compression.
The L1D test data contain in netCDF format the same information as the L1C data, but the radiances are compressed by using Principal Components. The data format is explained in the Product Format Specification document, made available along with the test data.
These test data are intended for format familiarisation and system testing.
