Read the FAQ if you encounter any problems. If they do not resolve your issues, please contact the developers.
How to run

Calculate totals over all time steps, levels and grid cells:
nes total -i input.nc
nes total -i input.nc -l NOx CO
Omit -l to include all data variables. Each line prints the variable name,
total and original units. NaNs are ignored; no unit conversion or area/time
integration is applied. Missing units are shown as unknown units.
Releases
Stable source releases are available on GitHub. Published Python packages are available on PyPI.
