COMPARISON OF SULFATE CONCENTRATIONS SIMULATED BY TWO REGIONAL-SCALE MODELS WITH MEASUREMENTS FROM THE IMPROVE NETWORK
Irwin, J. S., E. L. Gego, C. Hogrefe, J. M. Jones, AND S T. Rao. COMPARISON OF SULFATE CONCENTRATIONS SIMULATED BY TWO REGIONAL-SCALE MODELS WITH MEASUREMENTS FROM THE IMPROVE NETWORK. Presented at 9th Harmonization Conference, Garmisch-Kartenkirchen, Germany, June 1-4, 2004.
The goal of this task is to thoroughly characterize the performance of the emissions, meteorological and chemical/transport modeling components of the Models-3 system, with an emphasis on the chemical/transport model, CMAQ. Emissions-based models are composed of highly complex scientific hypotheses concerning natural processes that can be evaluated through comparison with observations, but not validated. Both performance and diagnostic evaluation together with sensitivity analyses are needed to establish credibility and build confidence within the client and scientific community in the simulations results for policy and scientific applications. The characterization of the performance of Models-3/CMAQ is also a tool for the model developers to identify aspects of the modeling system that require further improvement.
