Problem With remapbil
Added by praveen rai over 2 years ago
Hello,
I am trying to remap my model data using a reference file to convert it to normal lonlat grids. It works well with it one of the output file but with second file a warning pops up and somehow my domain gets distorted. This is the warning from CDO:
cdo remapbil (Warning): Source grid cell center latitudes out of range (min=43.8/max=90.7)!
Any help will be highly appreciated.
Thanks
Praveen

The lon/lat coordinates are interchanged, since both have the same units "degrees_north". The longitudes should have the units "degrees_east".
ncdump -h Precip_2000.nc
netcdf Precip_2000 {
dimensions:
time = UNLIMITED ; // (2 currently)
bnds = 2 ;
rlon = 257 ;
rlat = 271 ;
variables:
double time(time) ;
time:standard_name = "time" ;
time:bounds = "time_bnds" ;
time:units = "day as %Y%m%d.%f" ;
time:calendar = "proleptic_gregorian" ;
time:axis = "T" ;
double time_bnds(time, bnds) ;
double lat(rlat, rlon) ;
lat:standard_name = "longitude" ;
lat:long_name = "longitude coordinate" ;
lat:units = "degrees_north" ;
lat:_CoordinateAxisType = "Lon" ;
double lon(rlat, rlon) ;
lon:standard_name = "latitude" ;
lon:long_name = "latitude coordinate" ;
lon:units = "degrees_north" ;
lon:_CoordinateAxisType = "Lat" ;

Thanks Uwe. And to remove these, I think I have to use nco or is there a way to do it in CDO or is it possible to interchange lat/lon here in the file only?

NCO is the easiest way to change the attributes. Of course, the standard_name attribute must be changed as well.
