Problem Reading NAM12 beginning 9/30/2014

Post by kgebhart »

When I run ensemble trajectories using NAM12 data as input I have no problem when all the data are for 9/29/2014 and earlier. However, if I need data from dates later than that I get this message in the WARNING file: " WARNING metset: Old format meteo data grid 9 1" and the program crashes.

I had been running revision 346 from 2012 on both Linux and Windows 7. However, when I started getting the error message I downloaded the latest version of hysplit for Windows and I still get the same problem. I also noticed that the NAM12 files are slightly larger beginning on 9/30/2014. Did something change? Any work arounds?

Thanks!

We added a new field to the NAM12 Archive on September 30 (the planetary boundary layer height PBLH) and this caused a problem with our decoder. On November 7, we corrected the problem with the decoder as well as the data files from September 30 to November 6. You will need to re-download the NAM12 meteorological data files from September 30 through November 6 so that HYSPLIT can read them. This topic was also discussed here:
