The catalog is attached. You can get copies of the files from ftp://ftp.cdc.noaa.gov/Datasets/ncep.reanalysis/surface.Hi Roland,I haven't been able to reproduce this yet but I've been working with our 4.0 code, oops. I'll switch over to our 3.16 code. In the mean time, can you send me your config catalog so I can make sure I'm breaking things properly?Thanks, Ethan
As it says in the catalog, the descriptions and hierarchy are totally made up, but the geo-spatial metadata should match what's in the file.
