KANG, D., R. MATHUR, S. YU, AND K. L. SCHERE. EVALUATION OF ETA- CMAQ O3 FORECAST OVER DIFFERENT REGIONS OF THE CONTINENTAL US AND USING NEW CATEGORICAL EVALUATION METRICS. Presented at 28th NATO/CCMS International Technical Meeting, Lepzig, GERMANY, May 15 - 19, 2006.
Impact/Purpose:
The objectives of this task include: (1) to continuously evaluate and analyze the forecast results to provide diagnostic information on model performance and inadequacies to guide further evolution and refinements to the CMAQ model, and (2) extending the utility of the daily air quality forecast model data being produced by NOAA's National Weather Service (NWS) as part of a NOAA/EPA collaboration in air quality forecasting, to EPA mission-oriented activities. These objectives include developing and maintaining a long-term database of air quality modeling results (ozone and PM2.5), performing periodic analysis and assessments using the data, and making the air quality database available and accessible to States, Regions, RPO's and others to use as input data for regional/local scale air quality modeling for policy/regulatory purposes.
Description:
Developmental forecasts simulations with the Eta-CMAQ modeling system over the continental U.S. were initiated in 2005. This paper presents an evaluation of surface O3 forecast over different regions of the continental U.S. In addition, to the traditional operational evaluation metric, three new categorical metric are developed and applied to the Eta-CMAQ results.
