[Met_help] [rt.rap.ucar.edu #65423] History for Problem with MET V4.1 User's Guide

[John Halley Gotway via RT]

----------------------------------------------------------------
  Initial Request
----------------------------------------------------------------

I am running MET V4.1 Point-Stat and the V4.1 User's Guide (p.4-12) shows the following to specify the FULL grid area for the verification masking region:

mask = {
   grid = [ "FULL" ];
   poly = [];
   sid  = "";
};

When I run Point-Stat using this setting, it verifies over the region "FULL" but also attempts to verify over a second region "NA".

I looked at the default configuration file in the data/config/ directory and found that the setting is different:

mask = {
   grid = [ "FULL" ];
   poly = [];
   sid  = [];
};

I reran Poiint-Stat using this setting and it no longer attempts to verify over region "NA".

Recommend change to the setting shown on p. 4-12 of the User's Guide to replicate that shown in the default config file.

John,

Great, thank you for letting us know.  We'll update the user's guide.
The change in the way of specifying the station id (sid) list is due
to a change in how the code interprets its contents.

In earlier versions of MET, "sid" was just a single string containing
a file name.  That file contained a list of station names.  Each
station was treated as it's own "masking" region which usually
resulted in a single matched pair being found.  This came before the
addition of the matched pair (MPR) output line type.  Once we added
MPR, this type of masking by individual station id's was no
longer needed.  Using the MPR line type is an easier way of tracking
performance at individual stations.

In METv4.1, "sid" is now specified as an array of strings.  Each entry
in that array is either the name of a single station id or a filename.
If it's a single station id name, that station will be
treated as its own masking region, as in previous versions of MET.  If
it's a filename, that file should contain a "name" followed by a
space-separated list of station id's.  That first "name" entry
is what MET puts in the VX_MASK output column.  This provides a way to
define one or more groups of individual stations over which to compute
statistics.  This is an alternative to defining a masking
region using a polyline or grid and is more convenient if you have a
specific list of station id's you'd like to use.

Looks like we need to updated page 4-12 with this more detailed
information.

Thanks,
John
