The EPS-SG IASI-NG 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.
IASI-NG L1C and L1D
The IASI-NG L1C and L1D test data are available on our sftp site:
The IASI-NG L1D test data set is generated using the IASI-NG L1D In-house Prototype Processor using IASI-NG L1C test data and auxiliary data as input. The input L1C test data provides the geolocated real spectrum and other information required for generating the L1D data.
Both IASI-NG L1C and L1D test data are in netCDF format and they are described in the following documents available with the package:
The test data link above also includes the auxiliary data which contains full resolution, original L1C radiances of any outlier spectra. The auxiliary data also contains the mean and standard deviation of the compression residuals computed over all non-outlier spectra of the output product.
The following documents available in the test data package describes the content of the auxiliary data.
The IASI-NG L2 test data V2.1 is generated using the IASI-NG L2 In-house Prototype Processor using L1D test data, L1C test data, MWS L1B test data and auxiliary data as input.
The IASI-NG L2 test data is available on our sftp site:
The L2 data follows the format specifications provided in the following documents, which are available together with this release package.
The Readme file gives more details on the data package.
Note: all old versions are obsolete for format familiarisation purposes.
These test data are only intended for format familiarisation and system testing.
The IASI-NG L1C test data are generated in the frame of a cooperation between EUMETSAT and CNES in the context of IASI-NG observation mission
