Description

I have installed Flexpart V10.4 along with Flexextract etc. on a Lubuntu 20.04 system. So far as I can see the installation went well. To proceed with testing my aim was to run the first example described in Pisso et al. (2019). I have used Flex_extract to download the relevant input met data:

$flex_extracthome/Python>./submit.py
 --start_date 20170102  --controlfile
   CONTROL_EA5

and this succesfully results in the EA17010200 etc. files. I then proceeded to amend the pathnames file to point to the correct locations and run Flexpart. Since I assumed the AVAILABLE, OUTGRID, COMMAND and RELEASES files etc. sent with Flexpart would match this example I did not edit them. However, these example files do not match and it seems they are for another date (20120101). Given this I attempted to amend the relevant input files to match the met data I had downloaded. Having done this I have managed to get past many of the initial errors. However, I am now stuck with a series of GRIB1 and GRIB2 message errors e.g.:

***WARNING: undefined GRIB2 message found! 192 128 27 1 parID 27 isec1(6)
***WARNING: undefined GRIB2 message found! 192 128 28 1 parID 28 isec1(6)
***WARNING: undefined GRIB2 message found! 192 128 244 1 parID 244 isec1(6)
***ERROR: input file needs to contain GRIB1 formatted messages

I would appreciate knowing how to resolve this issue. That or which met data I should download to match the other input files associated with Flexpart V10.4.

One other point, I also get the following note:

Note: The following floating-point exceptions are signalling: IEEE_DENORMAL

Perhaps this is related and points to other issues I may have?
