[x] add the time dimension (as a "record dimension")
[x] rename coordinates and dimensions from x / y to lon / lat
[x] ds.sortby('y') was needed so I could do plots in xarray/cartopy. At least xarray didn't like the inverted order in the coordinates (it explains why we kept getting blank output when plotting)
[x] we don't need to retain 2D lat/long grids. That reduced file size by a lot
[x] convert March 19, 2008 geotiff to NetCDF (currently in /att/nobackup/aarendt)
ds.sortby('y')
