problem when transfering from grib format to netcdf

Added by Delei Li over 10 years ago

Hi all,

I am trying to transfer a file with grib format to netcdf format, the file is attached. The command I used is: cdo -R -r -f nc copy 2006022000.grb 2006022000.nc
The error is: Error (cdfDefGrid) : Unsupported grid type: lcc. Does anyone know how to solve this problem?
Thanks very much in advance.

Best regards

try the NCL utility: "ncl_convert2nc 2006022000.grb"

apparently CDO cannot convert your GRIB since the grid type is unsupported (Lambert Conformal projection)

The Lambert Conformal projection can be converted to geographical coordinates on a curvilinear grid:

cdo -f nc setgridtype,curvilinear file.grb file.nc
The NCL utility ncl_convert2nc does the same conversion.
