Three models
EVALUATION OF
REGIONAL MODELS ASSIMILATED DATA SETS
Introduction
This work is in support of GCIP's principal goal to evaluate land surface/atmospheric
parameterizations from regional numerical weather prediction models. The
Web Page describes work aimed at evaluating the output products of three
such regional models:
(1) Eta, from the Environmental Modeling Center EMC/NCEP,
(2) MAPS (Mesoscale Analysis and Prediction System) developed by the Forecast
Systems Laboratory (FSL) and
(3) GEM (Global Environmental Multiscale Model) of Atmospheric Environmental
Service from Canada.
Such an evaluation is expected to:
Help produce improved estimates of water and energy cycles over the Mississippi
and LSAs.
Help the developers evaluate the results of the physical packages in each
of the models and, when available, to validate their results with observations.

Earlier tests:
A three day sample taken in mid-May 1996 was used to perform a preliminary
analysis to detect, eliminate, or at least reduce, possible problems that
might arise in later stages of the evaluation. A Memo was prepared with
our findings and distributed among the modeling groups. (

A second three day sample was taken in mid-March 1997. This Page reports
on what was found from that sample. Email messages to each group will be
sent with specific comments on the samples.
