[ncl-talk] regrid CCSM4 curvilinear grid to another curvilinear grid

[Brandon Fisel]

Hello,

I would like to regrid CCSM POP data onto another grid, but I am unsure
where to begin as the destination grid has (i, j) coordinates that do not
correspond to lat, lon. Running cdo sinfon:

Source (ccsm) grid:
   File format: netCDF2
    -1 : Institut Source   Ttype    Levels Num  Gridsize Num Dtype :
Parameter name
     1 : unknown  CCSM     instant      1   1    122880   2  F32  : SST
   Grid coordinates :
     2 : curvilinear  > size      : dim = 122880  nx = 320  ny = 384
                        TLONG     : min = 0.0147311016  max = 359.99602
 degrees_east  circular
                        TLAT      : min = -79.2205226  max = 89.7064096
 degrees_north
                        available : xvals yvals

Destination grid:
   File format: netCDF
    -1 : Institut Source   Ttype    Levels Num  Gridsize Num Dtype :
Parameter name
     1 : unknown  unknown  constant      1   1   1684800   1  F32  : TEMP
   Grid coordinates :
     1 : generic      > size      : dim = 1684800  nx = 1560  ny = 1080
                        I         : first = 1  last = 1560  inc = 1  degrees
                        J         : first = 1  last = 1080  inc = 1  degrees

I have tried using ESMF regridding, but I am unable to plot the regridded
data due to allocation limits (workspace reallocation exceeding the maximum
size 60000000), and do not trust the data has been correctly regridded.

Any help or ideas where to begin would be appreciated. Thanks in advance.

Cheers,
