Hi Robb,

Could you check out the following GRIB table reference?  Based on what I'm
seeing in the data files, I could believe that the reference is correct
(i.e. 130 is MSLP and 238 is snow cover percent).

Let me know what you think,


Tom,
it looks reasonable to me, i added parm 130 and 238. this table stuff is a pita. 

robb...





Thanks!
Tom.

Hi,

Sorry for the delayed response.

The  website (http://www.nco.ncep.noaa.gov/pmb/docs/on388)
shows GRIB Parameters and Units under Section 1 Table 2.
The first section shows Parameter Table Version 2.  If
you scroll down in that table to 128-254 it says reserved
for use by originating center.  Then it says

NWS/NCEP usage as follows...

The originating center for 7 is NCEP so, even though this
is not Version 129, I think this is what you would use.  I
have posed this question to the WPP maintainer and I will
let you know what she says when I hear back.  In the
mean-time I would say try Table 2.

Hi,



In our continued efforts to work with the results of
WRF-POST, we have
encountered two parameters in the grib file that we
cannot find
corresponding grib tables for - these are



    :GRIB_center_id = 7;

    :GRIB_table_id = 129;

    :GRIB_param_number = 130;



and:



    :GRIB_center_id = 7;

    :GRIB_table_id = 129;

    :GRIB_param_number = 238;



Have you any idea where we can find the grib table (s)
that contain these
parameters?



Thanks!
Tom.
