[ncl-talk] ESMF_Regrid question

[Barry Lynn]

Hi:

I am trying to regrid WRF.nc output to rectilinear coordinates.

The code stops partway through.  It is strange because the code is already
curvilinear, but the regrid program seems confused because my array sizes
are equal (the code is attached below)

Working on time: 2016-01-23_12:00:00
(0) get_src_grid_info: source lat dims = (624,624)
(0) get_src_grid_info: source lon dims = (624,624)
(0) get_src_grid_info: *source grid type is 'curvilinear'*
(0) curvilinear_to_SCRIP: calculating grid corners...
(0) curvilinear_to_SCRIP: no lat values are at the poles, so
(0)       calculating grid corners using
(0)       calc_SCRIP_corners_noboundaries...
(0) calc_SCRIP_corners_noboundaries
(0)     min/max original lat: 26.0474/49.7817
(0)     min/max original lon: -94.1364/-58.8636
(0) calc_SCRIP_corners_noboundaries
(0)     min/max Extlat2d: 26.0071/49.8189
(0)     min/max Extlon2d: -94.2034/-58.7966
(0) calc_SCRIP_corners_noboundaries
(0)     min/max ExtGridCenter_lat: 26.0272/49.8003
(0)     min/max ExtGridCenter_lon: -94.1699/-58.8301
(0) get_dst_grid_info: destination lat dims = (624)
(0) get_dst_grid_info: destination lon dims = (624)
(0) get_dst_grid_info: Error: the lat/lon arrays are both 1D and the same
length.
(0)   This could be a rectilinear or unstructured grid. P*lease set
'grid_type'*
*(0)   to 'rectilinear' or 'unstructured'.*

Lastly, must we really have two exact versions of the same file "a" and
"src_file?" The file "a" is the one usually processed by ncl.  In a program
I received, they were named the same, but I am not sure of the implications
of this.

The name to use for the NetCDF file that will contain the needed grid
description of the destination grid. *Do NOT set this to the original file
that contains your data! This is the name of the *new* destination
description file that will get written.*

*Thank you!*
