Description
I am using NCEP wind fields(from http://rda.ucar.edu/datasets/ds093.0/) to run flexpartv10.4. However, the model is unable to detect the metdata format. The model works fine with ECMWF fields.
Any help is appreciated.
thanks

In the flexpart source code, the gributils/class_gribfile_mod.f90 line 50, These are the official centre codes for NCEP and ECMWF in grib files.
INTEGER, PARAMETER :: CENTRE_NCEP = 7, CENTRE_ECMWF = 98
It uses center code to distinguish input data (https://apps.ecmwf.int/codes/grib/format/grib1/centre/0/). But in fact, the center code of NCAR/UCAR in the https://rda.ucar.edu/datasets/ds083.2 is 60. You may need to modify it.
That should be fixed by flexpart team.

Dear mqzhang,
Thanks for your comment. Yes, it solves the problem of metdata format detection.
But I ran into another error similar to https://www.flexpart.eu/ticket/305.
I am sorry but right now I have no time for this.
Have you checked whether your problem is already discussed in ticket:305 ?
If not, I think you could ask that question on the mailing list, you will not be the only person to use NCEP input data.
