Hi Lei,

the errors occur because the dimension variables lon_nv, lat_nv, lon_nt, lat_nt, lon_ne and lat_ne are missing in the data file. They are needed because the variables temperature, avor, rvor, geopotential, u_edge and v_edge depend on them (see their coordinates attribute).

ncdump -h 2d.nc

netcdf \2d {
dimensions:
    location_nt = 5120 ;
    location_ne = 7680 ;
    location_nv = 2562 ;
    nlev = 18 ;
    nmaxvnb = 6 ;
    nthree = 3 ;
    ntwo = 2 ;
    location_t = 5120 ;
    location_e = 7680 ;
    location_v = 2562 ;
variables:
    double temperature(location_v, nlev) ;
        temperature:long_name = "temperature" ;
        temperature:coordinates = "lon_nv lat_nv" ;
    double avor(location_t, nlev) ;
        avor:long_name = "avor" ;
        avor:coordinates = "lon_nt lat_nt" ;
    double rvor(location_t, nlev) ;
        rvor:long_name = "rvor" ;
        rvor:coordinates = "lon_nt lat_nt" ;
    double geopotential(location_v, nlev) ;
        geopotential:long_name = "geopotential" ;
        geopotential:coordinates = "lon_nv lat_nv" ;
    double u_edge(location_e, nlev) ;
        u_edge:long_name = "u_edge" ;
        u_edge:coordinates = "lon_ne lat_ne" ;
    double v_edge(location_e, nlev) ;
        v_edge:long_name = "v_edge" ;
        v_edge:coordinates = "lon_ne lat_ne" ;
}

Thank you Karin! Thank you very much!
