- Second, an interpolation software (scinecRegrid) is used to interpolate the regular Latitude-Longitude (LL) GRIB file on a regular Gaussian grid if requested. Scin ecRegrid is available at ECMWF, so at the moment users outside ECMWF can not use it. The SMOS_BUFR2GRIB proposes the option to skip the step2 (conveting the BFR files to a regular LL grid only).

In these examples the SMOS BUFR file s converted to GRIB on 07 February 2010 at 06 UTC (+/-3h). The input smosbufr is 1.1 Gb. It contains all the SMOS data.

The two brightness temperature output 0.25x0.25 GRIB files are each 0.208 Mb. The entire output (ten files) is 2Mb:
smosbufr_Faxx_0.25_angle30.grib: Faraday angle for XX polarised data
smosbufr_Fayy_0.25_angle30.grib: Faraday angle for YY polarised data
smosbufr_flagfov5_xx_0.25_angle30.grib: SMOS information flag, bit5 (AFOV), for XX polarised data
smosbufr_flagfov5_yy_0.25_angle30.grib: SMOS inforamtion flag, bit5 (AFOV), for YY polarised data
smosbufr_snpaxx_0.25_angle30.grib: Snapshot accuracy for XX polarised data
smosbufr_snpayy_0.25_angle30.grib: Snapshot accuracy for YY polarised data
smosbufr_snpqxx_0.25_angle30.grib: Snapshot quality for XX polarised data
