mpas_xarray.py

Wrapper to handle importing MPAS files into xarray (https://github.com/pydata/xarray)

Module does

1. Converts MPAS "xtime" to xarray time. Time dimension is assigned via preprocess_mpas.
2. Provides capability to remove redundant time entries from reading of multiple netCDF datasets via remove_repeated_time_index.

Example Usage:

from mpas_xarray import preprocess_mpas, remove_repeated_time_index

ds = xarray.open_mfdataset('globalStats*nc', preprocess=preprocess_mpas)
ds = remove_repeated_time_index(ds)

To test:

tar xzvf globalStatsShort.tgz
python mpas_xarray.py -f "globalStats*nc"

This outputs a simple time-series plot of Time vs. Time to test functionality.
