PLJ,

Happy to help.  There is a subtle problem in the "N3_W.nc" file you
sent me that is causing the problem.  The unixtime variable
attributes, init_time_ut and valid_time_ut, are stored as strings
while
the MET code is expecting them to be numeric.  Notice the double-
quotes around them in the output of ncdump listed below:

		APCP:init_time_ut = "1339826400" ;
		APCP:valid_time_ut = "1339826400" ;

If you look at their values in the other file you sent, "W_N.nc",
you'll see that they are numeric.  Notice that there are no double-
quotes:

		APCP:init_time_ut = 1339804800 ;
		APCP:valid_time_ut = 1339826400 ;

So if you modify the code that's creating the N3_W.nc file to write
the unixtime variables attributes as numbers instead of strings, that
should fix it.

Thanks,
John Halley Gotway

PLJ,

You'll have to be more specific when you say "Met can't read it".
Please send the exact command you're running and error message you're
seeing.  I ran the file you sent through the "plot_data_plane"
MET utility, and MET was able to read it just fine:

[johnhg at rambler]% METv4.0/bin/plot_data_plane
W_NAFP_C_ECMF_201204160000FD0000_0006.nc
W_NAFP_C_ECMF_201204160000FD0000_0006.ps 'name="APCP"; level="(*,*)";'
DEBUG 1: Opening data file: W_NAFP_C_ECMF_201204160000FD0000_0006.nc
DEBUG 1: Creating postscript file:
W_NAFP_C_ECMF_201204160000FD0000_0006.ps

I've attached the resulting plot - after converting it from postscript
to png format.

John
