Notebook and data for short xarray open tutorial presented at ICESat-2 Hackweek, Seattle, WA, 17 to 21 June, 2019.
The notebook contains a very short introduction to the python xarray package. Please see http://xarray.pydata.org/en/stable/ for a more in depth introduction and documentation.
I've included an example of vectorized indexing, which, for example, could be used to extract values from gridded data
along an ICESat-2 track. I've also included an example of how to interpolate an xarray field to a set of points. The
segtrax team use this to interpolate ice motion vectors to the locations of ICESat-2 sea ice freeboard segments. The
interpolation routine is based on one presented by Johan and Fernando Paolo.
