remap on a regular grid from projection
Added by matteo borgnino over 2 years ago
Hi,
I would like to know if it is possible to remap a netcdf from a rotated grid to a regular lonlat grid.
In particular cdo griddes myfile.nc returns:
gridtype = projection
gridsize = 1331716
xsize = 1154
ysize = 1154
xname = rlon
xlongname = "longitude in rotated pole grid"
xunits = "m"
yname = rlat
ylongname = "latitude in rotated pole grid"
yunits = "m"
xfirst = -5.10000000000002
xinc = 0.0113
yfirst = -8.0943
yinc = 0.0114
scanningMode = 64
How can I map myfile.nc on a regular lonlat grid with the same resolution?
Thanks

Hi Matteo,
maybe I'm wrong but for me it looks like a mixed grid description. The x- and y-axis longnames shows rotated pole grid and the units are meter but I would expect something like 'degrees_east' and 'degrees_north'. If it is a rotated pole grid the grid information is missing. Does your file contain a variable rotated_pole which contains the following attributes?
grid_mapping_name grid_north_pole_latitude grid_north_pole_longitude
