Atmospheric Transport and Dispersion Model Hierarchy. Part 2
Abstract
U.S. Army Dugway Proving Ground (DPG) conducted a methodology investigation to identify the numerical mesoscale modeling approach best suited for operational use in predicting DPG test grid winds up to 24 hours in advance. The selection criteria for the models were that they be: (1) existing models that have been successfully applied to mesoscale flows in complex terrain, (2) nonproprietary, and (3) available. The three models acquired during the study that satisfied these criteria were the U.S. Army Atmospheric Sciences Laboratory (ASL) model hierarchy, the Los Alamos National Laboratory (LANL) HOTMAC model, and Jan Paegle's BLAYER model. Initial work with the SIGMET model, the prognostic component of the ASL model hierarchy, identified a number of problems when the model was applied to DPG terrain with a grid resolution of 5 km.
