Paper Abstract

Regional scale, Eulerian framework air quality simulation models are currently being evaluated using pollutant and meteorological measurements from special surface networks and airborne p1atforms. An evaluation protocol for such models using this data base has been developed and adopted by the National Acid Precipitation Assessment Program; it includes "Operational" and "Diagnostic" components. This paper focuses on the diagnostic evaluation of the Regional Acid Deposition Model (RADM) , using aircraft measurements from the Acid Model Operational Diagnostic Evaluation Study (AcidMODES) program under sponsorship of the United States Environmental Protection Agency (USEPA) . RADM's ability to resolve horizontal patterns and gradients as well as the vertical structure of primary and secondary acidic pollutant species in the mixed layer over the major source region for sulfur and nitrogen emissions is an essential diagnostic test and is demonstrated. The potential roles of remote sensing in the evaluation of regional models are suggested.
