12km NAM data in online HYSPLIT

[jwkent]

I am encountering an error if I try to run online HYSPLIT for archived dispersion using 12km NAM data. For example, I wanted to do a dispersion run beginning at 03Z on 02 NOV 2014. I selected 20141102NAM12 data. On the Model Run Details page, the year/month/day options are inactive, presumably because I already selected the met data for a specific date. I set the time to 0300 and request dispersion run, and immediately get "Internal Server Error". I am able to use the 12km NAM data for forecast dispersion runs without an issue.

After investigation we found that there is a problem with the structure of the meteorological data file for the NAM12 archive for the dates from 09/30/2014 to 10/28/2014. We will attempt to recover and correct these files and will report back to this forum when they are corrected.

The data files have been corrected, so you should be able to use them with HYSPLIT now.
