Regional EARS-MWRI data is available on EUMETCast from today (15 April 2021).

The EARS-MWRI service provides data from the Micro-Wave Radiation Imager (MWRI) instrument, on board the FY-3D spacecraft, operated by CMA.

The service is supported by the EARS core stations: Athens, Kangerlussuaq, Lannion, Maspalomas and Svalbard.

The data are processed to level-1 using the CMA provided processing package (FY3_IPP). They are available in their native HDF-5 format and in BUFR.

Example filenames

HDF-5: W_XX-EUMETSAT-kan,mwri,DBNet+fy3d+kan_C_EUMS_20210322081643_mwri_20210322_0802_fy3d_17362_ear_kan_l1b.hdf
BUFR: W_XX-EUMETSAT-kan,mwri,DBNet+fy3d+kan_C_EUMS_20210322081643_mwri_20210322_0802_fy3d_17362_ear_kan_l1b_bufr.bin

Note: Differences between EARS-MWRI regional brightness compared to global data was found to be above acceptable thresholds for a minority of passes (20 to 30 %). The brightness temperature differences are below 0.3 K for these passes. In Svalbard for exceptional cases, the calibration was found to be out of scale for the first 112 scan lines of the brightness temperature. An investigation is ongoing with CMA to resolve these discrepancies.

The data will be distributed on EUMETCast as follows:

Channel: E1H-RDS-2
