[gradsusr] NARR Dataset - Precipitation

[Ling,Alister [Edm]]

Brian,
 
try running it first manually with as little defined as possible, that
is let grads assume all the defaults, then start refining the display. I
too have seen that error message because I had the wrong intervals or
gxout settings. Oh, first double check the name of the variables in the
ctl file, these often are something different than what I expected.
 
Best wishes,
Alister.

Brian, 
I'm not sure why you get undefined values for those downloaded
variables, but you may consider as an alternative accessing the NARR
directly with sdfopen.

For example:
ga> sdfopen
http://nomads.ncdc.noaa.gov:80/dods/NCEP_NARR_DAILY/201207/20120715/narr
-a_221_20120715_0000_000

	Hello,

	 

	I downloaded data from the NARR model and I'm able to extract
point data for all variables, except precipitation amount (APCP) and
categorical precipitation types (CFRZR, CICEP, CRAIN, CSNOW). When I try
to plot the precipitation amount data, it is saying "Cannot contour grid
- all undefined values", but when I run wgrib on the files, it is giving
me a range of values for those variables.

	 

	I would appreciate any insight.

	 

	Thanks
