To plot a particular parameter and level we need to filter the desired fields from the resulting FLEXPART output GRIB file. 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. |
...
In the macro first we define the level (8000 m) and the parameter ("mdc") we want to plot. Then we call the Macro Library Function mvl_flexpart_read_hl() to extract the data.
| Code Block |

dIn="result_fwd/" inFile=dIn & "conc_s001.grib" lev=8000 par="mdc" #Read fields on the given height level g=mvl_flexpart_read_hl(inFile,par,lev,-1,1) |
...
Next, we build the title with mvl_flexpart_title(). Please note that we need to explicitly specify the plotting units!
