  • The purpose of the MOS Verification web sites is to compare the results of the NGM and GFS MOS products from 4/1/2001 to now.  Currently they are broken up into a version 1 and a version 2.

    Version 1 is based on a large set of static .gif images per month per region.  Unfortunately a segment of our users wanted individual stations as opposed to region data, which made the static images impractical.

    Version 2 was developed so that users could choose individual stations, and a variable time range.  This requires CGI, and a database.  There is currently no official site for version 2, as we haven't managed to put it on the offical NWS weather.gov web site.  Instead, we have put it on a local experimental machine.  Since it is an experimental machine it occasionally may be unavailable.
