TAFB Update on Item #1:

I verified that the latest 12Z RWPS run made it in GFE for the Atlantic
domain, so the crons appear to be working. Unfortunately, the input data
availability on polar.ncep.noaa.gov for the Pacific domain is much less
reliable, so most of the time only the Atlantic RWPS output will be
available (if any).
