Shift longitudes

This tool wraps the functionality of shift-lon.py.

The wrapper aims at providing a simple utility to shift longitudes ranging from 0. and 360 degrees to -180. and 180. degrees. The input file must be in netCDF format with geographical coordinates (latitudes, longitudes) given in degrees.

What it does

This tools creates a netCDF file with the same variables as the original file but where longitudes range from -180. to 180.

Usage

usage: shift-lon.py [-h] [-v] input output

Positional arguments:

input: input filename with geographical coordinates (netCDF format)
longitude: variable name for longitudes as stored in netCDF file
output: output filename for data with shifted longitudes

Optional arguments:

-h, --help show this help message and exit

-v, --verbose switch on verbose mode

It uses xarray python package to generate plots. More information about xarray can be found at http://xarray.pydata.org/en/stable/

`-h, --help`	show this help message and exit
`-v, --verbose`	switch on verbose mode
