Command-Line Interface

The NES CLI allows you to run core operations such as reordering longitudes and checking data directly from the command line. Once NES is installed, the nes command becomes available in your terminal.

The following commands are registered in NES 1.3.5:

Command	Description
check	Check for NaN and Inf values in a NetCDF file
reorder	Convert longitudes from [0, 360] to [-180, 180]
nc2geostructure	Convert a NetCDF to a geostructure (GeoJSON, Shapefile)
nc2rline	Convert a NetCDF into RLINE format
check_min_max	Check validity of minimum and maximum values for a variable of a NetCDF
plot	Generate a variety of plots for visualization purposes for a certain NetCDF variable
mask	Compute the applied mask to a NetCDF file and write the result to a new NetCDF file.
diff	Compute signed differences: comparison minus baseline
diffper	Compute percentage differences relative to a baseline
gridarea	Calculate grid cell areas and write a NetCDF
interpolate	Experimental registration; current CLI handler is not operational
