Example Say infile contains fields on a quadrilateral curvilinear grid. To remap all fields bilinear to a regular Gaussian F32 grid, type: cdo remapbil,F32 infile outfile CDO Grid Description Files The critical part of remapping with CDO is to create horizontal-grid description files describing both your input and output grids. First create a grid file. cdo remapbil,r360x180 in. txt For more details you can refer to my video guide on interpolation. This module contains operators for a bilinear remapping of fields between grids in spherical coordinates. nc). 46s* 6682MB].

The problem now is that my example file has a high resolution and the file I'm trying to convert changed from 500 MB to 31 GB. For a detailed description of the interpolation method see SCRIP. nc Actually this happens to some CMIP6 models (here we are trying to remap CNRM May 18, 2020 · remapbil : bilinear interpolation remapnn : nearest neighbour interpolation remapcon : first order conservative remapping remapcon2 : 2nd order conservative remapping You can use a grid descriptor file to define the area you need to interpolate to in the file grid. de/projects/cdo/files. nc The in. nc infile_fixedgrid. Here we just give a few examples for the use with CM SAF data: May 31, 2023 · Redmine « Previous 1 2 3 … 5 Next » (1-500/2344)Per page: 25, 50, 100, 500, 1000, 5000 Also available in: Atom Redmine Get public help Redmine Redmine « Previous 1 2 3 … 5 Next » (1-500/2344)Per page: 25, 50, 100, 500, 1000, 5000 Also available in: Atom The solution that worked was "cdo remapbil,grid_example. This interpolation method only works on quadrilateral curvilinear source grids. nc You should then be able to regrid the file. zmaw. hdf output. nc is as enclosed (zos_Omon_CNRM-CM6-1_abrupt-4xCO2_r5i1p1f2_gn_185009-185912. This is the same as the one you give, but with "generic" replaced by "lonlat": cdo griddes infile. nc > mygrid sed -i "s/generic/lonlat/g" mygrid Then use CDO to set the grid: cdo setgrid,mygrid infile. cdo remapbil: Bilinear weights from curvilinear (6844x3980) to lonlat (6201x3001) grid, with source mask (1942768) cdo remapbil: Processed 2 variables over 1 timestep [*47. cdo -f nc remapbil,r360x180 -import_cmsaf cmsaf_product. nc (importing CM SAF data, bilinear remapping to a predefined global grid with 1° resolution and conversion to netcdf). Jun 15, 2021 · You can solve this using the setgrid operator. nc". These files provide the latitude and longitude of every grid point, and of the corners of its surrounding cell boundary. Probably I need a example file with a resolution more similar to T126, or I need to change the method. The interpolation is based on an adapted SCRIP library version. Jun 8, 2025 · This module contains operators for a bilinear remapping of fields between grids in spherical coordinates. There is a line of missing values in the out. nc if. nc of. When I try to use remapbil this reported : cdo remapbil (Abort): Bilinear/bicubic interpolation doesn't support unstructured source grids! And when I use your recommendation the message is : cdo remapcon: SCRIP first order conservative weights from unstructured (104431) to lonlat (180x91) grid cdo remapcon: Target grid area error: 1345 -0. Learn how to use CDO, a software for standard processing of climate and forecast model data, with GRIB, NetCDF and MPI-MET formats. nc out. For an overview over the full functionality of the CDO package, please refer to the manual that is available at https://code. See examples of operators, file conversion, variable selection, data manipulation and more. Here are the out.
