    Grib2 interpolation issue

    Hello,

    I have an issue with a grib2 file. It reads correctly at each timesteps but somehow falls to zero (wind speed) between 2 timesteps. For instance if the file contains hours: 00h00m and 01h00m and I look (or route) at time 01h10m, the vector seems correct in direction but not in magnitude. 
    Looks like there is something wrong in the grib file that makes the Exp interpolation not working correctly but I can't see what.

    Can someone help with this ?
    Of course I can forward the grib2 file if needed.

    Best regards,

    Email me the grib file with a description of what you are seeing.

    It is a non-linear interpolation.
