ncregrid - Regrid Single Irregular NetCDF Grid

Overview

ncregrid can regrid a
structured/irregular/warped grid very quickly to a equirectangular
(Plate Carree) grid to simplify visualization workflows. It first
creates a map file from coordinate grids, and then performs fast
approximate nearest neighbor spatial index lookups when regridding
data values. 3D time varying variables are supported.
Unlike ncmerge, this operates
on just a single grid, instead of tiles spread amongst separate files.

Example

#  Create map file once.
ncregrid --map map.nc --eta -g xy.nc -x lon -y lat --nx 1000 --ny 500

# Do the regridding.
ncregrid --map map.nc --eta -i data.nc -v myvar -o output.nc
