DAILY SIMULATIONS OF OZONE AND FINE PARTICULATES OVER THE NORTHEASTERN UNITED STATES: MODEL PERFORMANCE, SEASONAL DIFFERENCES, AND THE EFFECT OF MODEL UPDATES. Presented at NOAA/EPA Golden Jubilee Symposium on Air Quality Modeling and Its Applications, Durham, NC, September 20 - 21, 2005.
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:
This poster presents analysis of near-realtime air quality simulations over New York State for two summer and one winter season. Simulations were performed as a pilot study between the NOAA, EPA, and NYSDEC, utilizing resources from the national operational NOAA/EPA air quality forecasts. Model simulations were compared against measurements of O3 and total and speciated PM2.5 as well as against routine air quality forecasts issued by NYSDEC.
