set grid type from curvilinear to lonlat
Added by Frosi Ma over 6 years ago
Hello,
I am trying to set my grid type from curvilinear to lonlat, but
cdo setgridtype,lonlat exp.nc lonlat-exp.nc
fails, because it only works on global data - mine is regional.
Here is an excerpt from my cdo sinfo:
Grid coordinates :
1 : curvilinear : points=62500 (250x250)
lon : 45.64614 to 108.1123 degrees_east
lat : -6.67273 to 44.8 by 0.1974667 degrees_north
Can somebody please help me?
Or is the only solution to interpolate to another grid?
Thank you very much
Kind regards
Frosi

lonlat is a special case of a curvilinear grid where the increment in lon and lat are constant.
This is not the case in your example file. In this case you have to interpolate the data.
