Release of simulated EPS-SG 3MI test data

EUMETSAT Polar System-Second Generation (EPS-SG) simulated 3MI Level 1B test data are now available for user familiarisation.

Wednesday, 19 February 2020

The EPS-SG Multi-Viewing Multi-Channel Multi-Polarisation Imaging (3MI) instrument is a passive optical radiometer dedicated primarily to aerosol characterisation for applications in climate monitoring, atmospheric chemistry, and Numerical Weather Prediction (NWP).

Test data description

The 3MI Level 1B test data are available here:

The L1B test data are generated from L1B1 data using the L1B Ground Processor Prototype V2.2 (GPP V2.2), which has been developed within a cooperation between EUMETSAT and CNES. The data up to L1B1 data were generated using the v2.1.3 IDS/GPP from ESA.

The L1B top of atmosphere (TOA) spectral radiance in reflectance factor unit is available to users in netCDF format. The test data are accompanied by a Product Format Specification document (PFS), which explains the numbering of the channels and the acquisition order as well as the product content.

These test data are intended for format familiarisation and system testing.

Documentation available via FTP:
