Model vs Obs Lat Lon plots of U200

[JulioTBacmeister]

New feature type

New plot and/or plot enhancement

What is this new feature?

I'd like maps of U200 (Zonal wind at 200 hPa) vs reanalyses - ERA5 or MERRA would be fine.

Assistance required?

Yes, I am requesting a new feature but won't have time to develop it

I recently added monthly mean U from ERA5, and it has 200hPa. So this should be working already, I think. Maybe @justin-richling can check if it actually does work.

Indeed, it does appear that U200 works with the new obs @brianpm put in recently.

@JulioTBacmeister Are you just wanting to compare the zonal winds between CAM and ERA5 at 200 hPa using the U variable from CAM? If so then @brianpm is correct that we already have that functionality.

However, if you are looking specifically for a comparison between the U200 CAM output variable and ERA5 or MERRA then yes, it looks like we'll need to create a new ADF variable defaults entry and obs variable or obs level selection option in order to do so.

@nusbaume -- That's right, I didn't think about that distinction (U200 in the CAM output vs specifying the 200hPa level with plot_press_levels).

Thanks. This looks good. I just wanted a comparison of U200 from CAM against any reanalysis. I'm not picky. It would also be nice to add U200 to the exp vs CTL plots.
