> HYSPLIT error message with old format meteo data grid
I purchased FNL meteorological files from NCDC for 1998, and they sent me a tape with
the files. When I run the HYSPLIT model however, I get the following message:
HYSPLIT4 (Dec99) - Initialization
Warning metset: Old format meteo data grid
forrtl:severe:Program Exception -access violation
Do you think there is a problem with these files or with the installation?
The trouble you are having is most likely due to some corruption of the meteorological
data. The message indicating "Old Format" data means that the model doesn't see an INDEX
record as the first record of the data set. Data after 1995 all have index records. There
are several utility programs in the \Hysplit4\metedata directory. I suggest you try
chk_rec.exe from the command line prompt. It should return ouput as follows:
The code is provided in the ..\source directory. It is a simple program and lets you
examine the structure of the meteorological data file. The index record is always the
first record and is indicated by the field "INDX" You should check out other data files
that you know work correctly to examine the differences.
The problem is either with the tape or the process used to transfer the data from the
tape to your computer. You need to be sure that the software you used to read the
tape did a "binary" rather than ASCII read.
