Due to the current gap in continued funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program Center has temporarily paused most operations. See NSF Unidata Pause in Most Operations for details.
All,We have noticed a strange problem with the grids coming in for the 0.5 degree GFS files. The problem started with the 12 UTC run of the 2015/04/22 run, and several files (though not always the same ones) have been missing grids in each run since. The complete files contain 366 grids, the incomplete files always contain 327 and are always missing exactly the following grids:
5WAVH 5-Wave Geopotential Height [gpm]:500 mb ABSV Absolute Vorticity [1/s]:100 mb ABSV Absolute Vorticity [1/s]:975 mb CLWMR Cloud Mixing Ratio [kg/kg]:150 mb CLWMR Cloud Mixing Ratio [kg/kg]:550 mb CLWMR Cloud Mixing Ratio [kg/kg]:800 mb CSNOW Categorical Snow [-]:surface: DLWRF Downward Long-Wave Rad.

One curious thing, the files are complete on motherlode.ucar.edu, but the files that we have as short, have a later modification time than the rest. For example, for the 12 UTC 23 run, we were missing grids for the F021, F102, F123 and F252 times. Here's a subset of the times on motherlode that shows these files:

Ideas?Here is a (I think) complete list of the times that had short files since 12UTC 4/22. I'm guessing all of these files are complete on motherlode, but have a later modification time than the rest of the run.
