You will very likely get a more robust response from Steve Chiswell or
someone who really knows what they are doing - but in the meantime - I
belive NIDS files should be ready to read by GEMPAK.
Try the gpmap program - set your map=1, garea=dset, proj="",
and run the program. If it displays it works, if not, you may need to
convert this to a different format or use a differnet gempak program to
plot the data that I am unfamiliar with.
Regarding your second question - there are no tools to take a current
snapshot of the atmosphere in gridded form and "prog" it into the future -
even by simple advection. GEMPAK is a display tool only - no dynamical or
even simple methods to step a current state of the atmosphere into the
Although - THAT would be cool. You may want to consider using the
workstation WRF to help with this exercise. This is a workstation version
of WRF. See http://strc.comet.ucar.edu/wrf for details on the type of
system required, data inputs, and other info you will need to get off run

Hi everyone, I am brand new to this list.
If my questions have already been answered, please inform
me of where I can find a message list archive. (I am very
new to GEMPAK)
How do I make NIDS files available for viewing within
NMAP. I have the following information:
The filenames appear as:
The NIDS files are on a 2km grid in a Lambert Conformal
projection, with a grid size of 2560 by 1792. The centre
lat/lon is 39/-98. Output reference lat1 is 33 and output
reference lat2 is 45. The NIDS product code is 140.
Secondly, I have a gridded mosaic of Canadian radar data
which I would like to translate via the 700hPa GEM
regional model wind field. My goal is to create a very
short term nowcast. Are there any tools within GEMPAK
which would allow me to do this or has anyone else
attempted to perform a similar task?
