NMAP Loops (#1562)

[Charley Knoderer]

Hi,

Here's the listing I get off of gdinfo:

 GEMPAK-GDINFO>l
 GDFILE   = 07021918_nam_212.gem
 LSTALL   = YES
 OUTPUT  
 GDATTIM  = all
 GLEVEL  
 GVCORD  
 GFUNC   
 GEMPAK-GDINFO>r

 GRID FILE: 07021918_nam_212.gem

 GRID NAVIGATION:
     PROJECTION:          LCC
     ANGLES:                25.0   -95.0    25.0
     GRID SIZE:          185 129
     LL CORNER:              12.19   -133.46
     UR CORNER:              57.29    -49.39

 GRID ANALYSIS BLOCK:
     ANALYSIS TYPE:        BARNES
     DELTAN:               4.000
     DELTAX:           -9999.000
     DELTAY:           -9999.000
     GRID AREA:            11.00 -154.00   62.00  -48.00
     EXTEND AREA:          11.00 -154.00   62.00  -48.00
     DATA AREA:            11.00 -154.00   62.00  -48.00

 Number of grids in file:  9210

 Maximum number of grids in file:  29999

 [GDU 2]  Did not find any matching grids.
 Parameters requested: GDFILE,LSTALL,OUTPUT,GDATTIM,GLEVEL,GVCORD,GFUNC.

To add further confusion to the matter, we have one machine running
gempak 5.7.3 and it displays the first time period in nmap, but only the
first time period.  On a separate machine, we are running gempak 5.9.4
and reading the decoded grib from 5.7.3 and nmap will not read these
files at all.

Any suggestions?

Thanks,
Charley

Charley,

Check your "GDINFO" listing of your decoded file. Your statement about
the "first" time period being missing may indicate that the source of
your grids changed from using the PDS identifier for F000 to an analysis
time . The Jan 22 time frame is coincident with changes in the mainframe
at NWS. If that is the case, try upgrading to 5.9.4.
