Dear GEMPAK Users,
I'm attempting to create a radar mosaic/composite on my WRF model forecast
domain, and I have not yet been successful with this undertaking. At first, I
considered using nex2img or nex2gini to take Level III radar products from NCDC
and mosaic them. However, I would like to be able to create a multi-panel
display of forecast reflectivitiy and observed reflectivity in a single GIF
image.
So, I switched to GDRADR, which looks to be the program I want to use. So far,
I have 2 radar sites and it appears that I have set up all the environmental
variables correctly. I have the archived base reflectivity data with the
following naming convention: $RAD/NIDS/%SID%/%PROD%/%PROD%_YYYYMMDD_HHMM
where %SID% is the station ID of the radar site, and %PROD% is the product
name, in my case "N0R".
When I try to run GDRADR, I consistently receive a Segmentation fault. I've
tried both setting up the grid parameters and setting a CPYFIL -- both the same
result. Does anyone have a recommendation for me?
My parameter settings are given below.
Many thanks,
Jonathan
