Problems with merra2wrf

Hi all,

 

We are users of merra2wrf software but since the new changes of MERRA-2 we are not able to run it with the new files. We are getting this errors:

 

- With the const_2d_asm_Nx in the 3 different formats (NetCDF4, NetCDF4 Classic, HDF-EOS (MERRA Format)

 

./merra2wrf namelist.merra2wrf

Reading file set  1 ...
    const_2d_asm_Nx
ERROR opening HDF4 file ./MERRA2_101.const_2d_asm_Nx.00000000.nc4
STOP 1

 

We have tried to use the const_2d_asm_Nx of MERRA and it works, but then we got this errors with the other files:

 

HDF-EOS (MERRA 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

 

 

NetCDF4

./merra2wrf namelist.merra2wrf
Reading file set  1 ...
    const_2d_asm_Nx
    inst6_3d_ana_Nv
Segmentation fault

 

 

NetCDF4 Classic

./merra2wrf namelist.merra2wrf

Reading file set  1 ...
    const_2d_asm_Nx
    inst6_3d_ana_Nv
Segmentation fault

 

Thank you a lot,

    There is another namelist file you need to use for using MERRA2 re-analysis data.

    In NUWRF  /utils/geos2wrf_2/namelist/namelist.merra2_2wrf  file is provided.

     

    ./merra2wrf namelist.merra2_2wrf

      Dear Mr. Jacob,

       

      I am Javier, a Carlos' colleague. We runned merra2wrf with the another namelist "namelist.merra2_2wrf" and it also failed. The error we obteined was the following:

       

      ./merra2wrf namelist.merra2_2wrf

      Reading file set  1 ...

          const_2d_asm_Nx

      netcdf: 65536 is not a valid cdfid

       

      We have been trying lots of things for several months without success. If you could help to us to solve the problem we were very grateful. Please, if possible tell us what files you would need to find out where is the problem. We thougth that the problem could be with the installation of libraries netcdf, hdf4, hdf5, zlib o szip. So we reinstalled them several times in several computers without succeded results.

       

      Thank you very much in advanced for your help.

       

      Sincerely,

      Javier Peña
