Unfortunately, Metview's Grib Filter icon cannot handle these files (partly due to the local GRIB definition they use) so we need to use other means to cope with this task. For this reason and also to make FLEXPART output handling easier a set of Metview Macro Library Functions were developed. We will use these functions in the example below. |

Next, we define the contouring. The "feflux" fields have the units of "kg m**-2 s**-1" but with the current value range "ng m**-2 s**-1" units would better fit for contouring. To achieve it this we simply multiply the "feflux" fieldset with 1012:
