    EUMETSAT have updated the nonlinearity correction for Metop-A IASI. You can find the new BRD file in the usual place, at ftp://ftp.eumetsat.int/pub/NWPSAF/aapp_data_files/OPS-LRS/aux_data/

    IASI_BRD_xx_M02_20190629000000Z_xxxxxxxxxxxxxxZ_20190628130814Z_IAST_0000000017

    As a reminder, the easiest way to install the latest files is to download and run the get_aux_files.sh script, which can be found in the same directory on the ftp site.

    I have also uploaded BRD updates that will be needed for Metop-B and Metop-C. These will have no impact on radiances. Details from EUMETSAT are as follows:

    In the coming weeks, 2 TOP upload are planned to replace the “Moon acquisition” coding table by the “routine” coding table on-board.

    – IASI-C => 17/10/2019 :
    IASI_BRD_xx_M03_20190830000000Z_xxxxxxxxxxxxxxZ_20190829125233Z_IAST_0000000014 (IDefIDConf = 17)

    – IASI-B => 22/10/2019 :
    IASI_BRD_xx_M01_20190906000000Z_xxxxxxxxxxxxxxZ_20190905080119Z_IAST_0000000016 (IDefIDConf = 49)

    There will be no impact on the level 1c radiances.
