[ncl-talk] Problem with regridding BNU-ESM (curvilinear) to rectilinear

[Morteza Qadimi]

Dear NCL wizards,

I want to regrid BNU-ESM (which is tripolar curvilinear) to rectilinear using ESMF_regrid. You can find my code below:

tas               = in->tas
lat2d           = in->lat
lon2d          = in->lon
sst at lat2d  = lat2d
sst at lon2d = lon2d
lat = fspan(-90,90,181)
lon = fspan(0.5,359.5,360)

Opt                = True

Opt at SrcGridType     = "curvilinear"
Opt at SrcFileName     = "ORCA_SCRIP.nc"
Opt at DstFileName     = "World1deg_SCRIP.nc"
Opt at WgtFileName    = "ORCA_2_World_SCRIP.nc"
Opt at ForceOverwrite = True
Opt at DstGridType       = "1deg"
Opt at DstTitle                = "World grid 1x1 degree resolution"
Opt at InterpMethod = “bilinear”


tas_regrid = ESMF_regrid(sst,Opt) 
printVarSummary(tos_regrid)

but I get an annoying error saying that:

fatal:Number of dimensions in parameter (1) of (curvilinear_to_SCRIP) is (1), (2) dimensions were expected
fatal:["Execute.c":8637]:Execute: Error occurred at or near line 3882 in file $NCARG_ROOT/lib/ncarg/nclscripts/esmf/ESMF_regridding.ncl

fatal:["Execute.c":8637]:Execute: Error occurred at or near line 4010 in file $NCARG_ROOT/lib/ncarg/nclscripts/esmf/ESMF_regridding.ncl

Any solution?
