Hi Brendon, Looks like i left you hanging, I did not see the question at the end...my bad ;) I ~think you will want to use the GFS 002 from the CONDUIT feed, it goes from hour 192-384. All the reg ex's and patterns for CONDUIT GFS are located at: https://www.unidata.ucar.edu/data/conduit/ldm_idd/ ..or for the GFS 002 it would look like: # Pipe all GFS Grid #002/#003 to decoder (note includes new NCEP file NAMES) CONDUIT (ST.opnl/MT.gfs|prod/gfs.*pgrb[^2]) PIPE decoder ..this is from: https://www.unidata.ucar.edu/data/conduit/ldm_idd/gfs_files.html Way sorry for keeping you on hold, thought we had closed the ticket :) Happy Monday, Jeff Jeff Weber Unidata User Support http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: DHE-868834 Department: Support IDD Priority: Normal Status: Open
