Hi Dave- > I'm running IDV v2.7b3 (the most recent nightly revision) on a MacBook > Pro laptop under Mac OS X v.10.5.7. > > I've been making plots of analyzed and forecast fields in the 2.5 > degree GFS model runs accessed via motherlode. I just noticed that > using the latest available GFS run (which happens to be 12Z June 22, > 2009), the plot times displayed under "Times" in the Dashboard and > everywhere else I've looked (e.g., display labels; Data Sources > > Properties > Times), are off by 8 days (too far ahead, so the analysis > is labeled or listed as 12Z June 30 instead of 12Z June 22). The GFS 2.5 global grid is the extended run and goes from days 8 to 16. They switch to a lower resolution for the extended forecast hours. I've attached a bundle that shows a loop with both the 80km GFS and 2.5 global GFS. Notice the continuity of the fields switching from the short term to the long term run. > I tried several other GFS model runs (including the most recent run > [June 22], the oldest available run [on May 8], and several chosen > randomly in between). I tried several different fields (geopotential > height, wind vectors). I tried quitting and restarting the IDV.
