Re: how to deal with an annual mean data

[1] The variable 'land_use' is of type "short".
     Please look at your data. You must unpack before using

      lu = short2flt(f->land_use) ; (time,lat,lon)
      printVarSummary(lu)

      lu_clm = dim_avg_n_Wrap( lu ,0 )
      printVarSummary(lu_clm)

[2] fatal:NclMalloc Failed:[errno=12

This says you ran out of memory.
