Create EarthNow vorticity plots

Recreate plots of voriticity, global and conus

[hannahzafar]

Global imagery with a basemap image (not the exact one found in EarthNow vorticity) has been generated. CONUS imagery is having an issue with the projection of the imagery, I suspect not encountered by global because of the LCC projection model files used for conus plotting.

Global plot generated:

CONUS plot generated (note the basemap projection issue evidenced by an upside down South America to the right of the image)

Evidence of CONUS Imagery using LCC model collections, see the following partial output when attempting to create CONUS imagery:

Versus the output in the global run:

@embell139 @srobe @jardizzo See my above comments for more details on the discussion we had today about the basemap imagery projection and conus vs global

Hi Hannah, so it is very evident that Bill pre-projected the data from the cubed-sphere. You can probably plot the data using matplotlib and cartopy by telling the codes that your data is pre-projected and then passing in the correct parameters to describe the grid. I have not done this using Python so I'm afraid we will have to learn how to do it. AI should help. You may want to try to make the plot from the global lat/lon data read and let Python project the data. That should yield a similar solution.

Notice that the LCC collection has a temporal resolution of 15 minutes. Bill may have been motivated by the requirement to resolve mesoscale features both temporally and spatially; hence the pre-projection and domain extraction.

@jardizzo I have fixed this now for conus. See the open PR #41
