Release of simulated EPS-SG Microwave Sounder (MWS) test data

EUMETSAT Polar System - Second Generation (EPS-SG) simulated MWS Level 1B and Level 2 test data are now available for user familiarisation.

Thursday, 12 December 2019

The MWS (Microwave Sounder) has a direct heritage from the microwave instruments AMSU-A (Advanced Micro-wave Sounding Unit A) and MHS (Micro-wave Humidity Sounder) on board EPS and NOAA satellites. Its primary objective is to support Numerical Weather Prediction at regional and global scales by providing information on atmospheric temperature and water vapour profiles in clear and cloudy conditions.

Test data description

The test data are available here:
ftp://ftp.eumetsat.int/pub/OPS/out/test-data/Test-data-for-External-Users/EPS-SG/MWS_Test_Data/

The Level 1B test data (EPS-SG_MWS-1B-RAD.nc.gz) contain the most important variables related to geolocation and calibration processing. These are listed according to the specifications given in the EPS-SG MWS Level 1B Product Format Specification document, made available along with the test data. The MWS L1B product, in netCDF format, is generated using the MWS L1B In-house Prototype Processor (IPP) developed at EUMETSAT.

The Level 2 test data (EPS-SG_MWS-02-TPW.nc.gz) are generated with the MWS L2 In-house Prototype Processor (IPP) using L1B data as input. The L2 data, in netCDF format, contain the geolocated total precipitable water (TPW) over water-surfaces, and limb-corrected brightness temperatures for all 24 MWS channels. The format and further content are described in the EPS-SG MWS Level 2 Product Format Specification document, made available along with the test data.

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