convert_mpas and Integrated Data Viewer (IDV) [SOLVED]

[alainF]

Hello,
I am using convert_mpas to generate latlon.nc netcdf files as outputs of my mpas simulation (from diag and history files). I tried to open the latlon.nc files with the Integrated Data Viewer.
Unfortunately, the viewer starts with a splash screen saying "no gridded data found".
I cannot figure out the reason, because the data are valid. I can open the latlon.nc files with Panoply.
IDV software can read netcdf files, so I don't understand.
Is there a way to solve the problem ? To convert .nc file format into .grib format ? Other ?

Thank you

The problem is solved.
The time is missing in latlon.nc. Panoply software doesn't care about that but IDV does.
So I have used CDO command. Suppose that the output of convert_mpas is renamed into latlon_diag.nc :

cdo settunits,hour -settaxis,2023-01-27,00:00:00,2hour latlon_diag.nc latlon_diag_taxis.nc

And now IDV is satisfied.
