Description
I'm trying to export 2d slices of wrf data to geotiffs, and have been stymied by the fact that:
-the projection information is not present in the .crs of the xarray object
-the projected coordinates of the upper-left corner of the upper-left pixel are not present in the attributes and do not seem to be otherwise accessible.
While we are able to extract the proj4 from a cartopy object created from the xarray data using wrf.get_cartopy , we have been unable to extract the projected coordinates of the upper left corner of the upper-left pixel. Without those coordinates, we cannot transform the data into an evenly spaced grid in order to export it to a raster dataset. Any help would be appreciated.
Best,
Isaac Park

Research direction
No source file or test is named. Start by tracing the xarray object's CRS and the wrf.get_cartopy path, then determine how projected upper-left pixel coordinates could be exposed for GeoTIFF export; done should provide a clear, usable way to obtain both pieces of metadata.
