Metview runs FLEXPART in a temporary directory. Having finished the simulation Metview converts and rename the output files and move them into the Output Path directory specified in the FLEXPART Run icon. FLEXPART produces a variety of outputs whicha re
The output metadata information is stored in a file called header( see writeheader.f)
Gridded outputs
Gridded outputs are converted to grib using a built-in local grib definition built-in into by Metview.
Concentration
...
- option: conc | pptv | time
- time: YYYYMMDDHHMMSS
- species: nnn
Concentration fields are only produced for forward simulations when Output Field Type is set to conc or both in FLEXPART Run.
The output filename is: cons_sSSS.grib where SSS is the species number (with leading zeros).

Dry and wt deposition
It is only produced for forward simulations when Output Field Type is set to conc, mixr or both in FLEXPART Run.

Wet and dry deposition is always zero in time. In conc and pptv files they are also zero but unless turned on internally (via WETDEP and DRYDEP). Whether WETDEP/DRYDEP is turned on or off depends on the given species.
