Does anyone know anyone at the NOAA ARL/who has anything to do with the NCEP/NCAR reanalysis data?

It looks like the 1948 and 1949 data have been mislabelled as 2048 and 2049 - noticed when running HYSPLIT trajectory models.

I've sent an email via the general NOAA research office, but not convinced it will get to the right people...

Question for you NOAA model experts out there (boosts welcome):

what is an easy (*) way to plot the RAP 13km domain data (https://rapidrefresh.noaa.gov/
) on a map using python/xarray/cartopy?

The high res domains are pretty straight forward, but the outer domain with its unusual grid does not work out of the box.

I can use wgrib2 to extract the record I want, but it ends up flattening the data into 1D and has no coordinates.
wgrib2 to netcdf segfaults, even though they seem to have added some support for the 'weird NCEP grid'.

I've found this approach: https://www.ssec.wisc.edu/realearth/solved-north-american-domain-rap-13-5km-rotated-pole-grib2-for-gis/

but I don't really want to work with a) that toolchain b) TIFFs - if I can avoid it.

Any ideas welcome.

(*) easy as in the least number of tools possible and only common ones. If it could be done with just wgrib2 and some python packages, that would be ideal.

Potential API Gridded Forecast Data Outage from December 22, 2024 through January 1, 2025

National Weather Service Headquarters | November 25, 2024

The Office of Dissemination (DIS) and the National Centers for Environmental Prediction (NCEP) Central Operations (NCO) continue to work on fixing a critical bug that disrupts the dissemination of gridded forecast data via the NWS Application Programming Interface (API) near the end of the calendar year. ... it is becoming more likely that the outage will occur. In the event that the bug fix cannot be implemented before December 22, technicians will disable the API...
