Well, this is the first time that I have had to setup NOGRIB.CFG (in the ~mcidas/uvaworkdata directory on your system) to _not_ decode certain grid forecast times. What I found isn't pretty (to say the least). I _think_ that I have turned off decoding of forecast hours for AVN and ETA that match your wish list above, but I will have to wait until the next runs are received to make sure what I did was correct. In order to allow for decoding to proceed, I generated a list of GRID files that contained data other than in your list above in /p4/data/xcd and deleted them. This freed up about 2 GB of disk space. Now, new grid decoding can resume. Just as a note, after making changes to ~mcidas/uvaworkdata/NOGRIB.CFG, I had to cause the McIDAS-XCD grib decoder to stop and restart. I did this as 'mcidas' as follows: cd ~mcidas/uvaworkdata decinfo.k SET DMGRID INACTIVE <wait for the DMGRID process to exit> decinfo.k SET DMGRID ACTIVE We will see by sometime tomorrow if the changes I made in NOGRIB were correct or not. One last comment. The version of McIDAS being run on windfall for ingesting/decoding is _OLD_! What is running is 7.6, and the current release is 7.8!! At some point, we _really_ should work together to upgrade your setup to the current release of the software. This is so that things that you have grown to depend on (like decoding of certain grids) will not begin to fail. I will not be in tomorrow as I am going skiing. I will read email early tomorrow morning and then after I get back. Tom
