Running WRF with MERRA2

[javier.p]

Dear Users,

The old source MERRA stopped production on February 29 and I have recently discovered the new source of reanalysis data MERRA2.
I used to run WRF using as input data MERRA. So, to process this kind of data I used the software MERRA2WRF. This application let you obtain the needed files to run metgrid.exe.
Unfortunately, I have tried to run MERRA2WRF using the files of the new source MERRA2 without success. When I run the script ./merra2wrf namelists.merra2wrf obtain the following errors:

Using the MERRA2 data in HDF-EOS (MERRA Format) format:
./merra2wrf namelist.merra2wrf
Reading file set 1 ...
const_2d_asm_Nx
inst6_3d_ana_Nv
ERROR, cannot find array in HDF4 file!
Looked for name XDim
With rank 1
And type 6
STOP 1


Using the MERRA2 data in NetCDF4 format:
./merra2wrf namelist.merra2wrf
Reading file set 1 ...
const_2d_asm_Nx
inst6_3d_ana_Nv
Segmentation fault

Using the MERRA2 data in NetCDF4 Classic:
./merra2wrf namelist.merra2wrf
Reading file set 1 ...
const_2d_asm_Nx
inst6_3d_ana_Nv
Segmentation fault

Does anyone know what it could be the problem?
or in case it was no possible to use merra2wrf to process MERRA2 data, does someone know if it exists any software similar to merra2wrf which let you use MERRA2 as input in WRF?

Thank you very much for your help.
Best regards,
Javier Peña
