I am trying to calculate zonal statistics (sums and averages within watershed shapes) using some tools in ArcGIS for netcdf. The tools require netcdf files to be in a regular grid. My source data is NARR data, which isn't being recognized as a regular grid (I believe it is curvilinear). So I am trying to regrid using templates provided on the ucar website. Attached is the code I am currently using. It gives me the following error. Despite search archives of this list, other responses have not resolved my problem. Help is very much appreciated, clearly there is something I am not understanding.</div><div><br></div><div><br></div><div><br></div><div>fatal:Eq: Dimension size, for dimension number 0, of operands does not match, can't continue</div><div><br></div><div><br></div><div><br></div><div><br></div><div><div>load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"</div><div>load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"</div><div>load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"</div><div>load "$NCARG_ROOT/lib/ncarg/nclscripts/esmf/ESMF_regridding.ncl"</div><div><br></div><div>;---Data file containing source grid</div><div> src_file = "<a href="https://urldefense.proofpoint.com/v2/url?u=http-3A__air.sfc.2009.nc&d=AwMFaQ&c=-dg2m7zWuuDZ0MUcV7Sdqw&r=uKbh2SXDxGKvLk5QzayNO82syruaWpicjIReiqrlroo&m=in-kyqdBB_SrcaUe8NduEiwvdug6jD8--IAlddvlGUM&s=ig9Wc1p8W1YxsWqkiFqci37YiabzbIhxeiyjz-uUzo0&e=" target="_blank">air.sfc.2009.nc</a>" ;;---Change (likely)</div><div> sfile = addfile(src_file,"r")</div><div><br></div><div>;---Get variable to regrid</div><div> varname = "air" ;;---Change (likely)</div><div> var = sfile->air</div><div> src_lat = sfile->lat ;;---Change (maybe)</div><div> src_lon = sfile->lon ;;---Change (maybe)</div><div><br></div><div>;---Set up regridding options</div><div> Opt = True</div><div><br></div><div>;---"bilinear" is the default.
