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 lc2:/raid1/casejl/DATA/RADAR > gdradr GRDAREA Area covered by grid 39.62;-91.83;49.57;-72.50 PROJ Map projection/angles/margins|dr lcc//6;1;1;2 KXKY Number of grid points in x;y 380;280 GDPFUN Scalar grid or vector grid funct N0R GDFILE Grid file rad.gem RADTIM Radar composite current/dattim 091209/1205 RADDUR Radar time window (minutes prior 10 RADFRQ Update Frequency CPYFIL Grid file whose navigation is to STNFIL Station information file nexrad.tbl MAXGRD Maximum number of grids 9999 RADMODE Radar operational mode pc NDVAL Replacement value for "ND" (defa Parameters requested: GRDAREA,PROJ,KXKY,GDPFUN,GDFILE,RADTIM,RADDUR,RADFRQ, CPYFIL,STNFIL,MAXGRD,RADMODE,NDVAL.
