clip.subsetNetCDF(filepath, bounds, newfilepath=None)[source]#

Crop a GOES-R ABI NetCDF file to latitude/longitude bounds.

Parameters

  • filepath (str) – path to a NetCDF file

  • bounds (list) – list or array containing latitude/longitude bounds like [min_lon, min_lat, max_lon, max_lat]

  • newfilepath (str) – path and filename for a new NetCDF file to write out to, defaults to None where it will overwrite the input NetCDF file

Examples

Subset a GOES ABI CONUS image so that we only have the western half of CONUS within latitudes 30 and 50, and longitudes -125 and -105.

>>> bounds = [-125, 30, -105, 50]
>>> subsetNetCDF('CONUS.nc',bounds,newfilepath='westernCONUS.nc')
