Multifunction Phased Array Radar: Potential Uses for Air Quality S.T. Rao Director, Atmospheric Modeling Division National Exposure Research Laboratory U.S. Environmental Protection Agency Research Triangle Park, NC 27711
Deliverables (NOAA and US EPA) that could be Improved by MPAR • Treatment of interactions between meteorology and atmospheric chemistry in air quality models • Improvements and modifications to air quality forecast models • Verification and Evaluation of model outputs. • Research, development, and operational model forecasts of meteorological and air quality parameters as determined by EPA and NOAA, on a real-time, routine basis, and on a national scale • Real-time ambient air quality monitored data • Emissions data and tools for the adjustment of annual emissions to be simulated daily emissions forecast applicable to the air quality simulation
MPAR: Development and Evaluation of Meteorological Models Used in Air Quality • General improvements of meteorological models by scientific community through a better understanding of the atmosphere • Improvements of PBL and surface layer parameterizations through high resolution MPAR 3-D wind fields • Potential source of much-needed PBL height observations at high spatial and temporal scales as well as turbulence characteristics of the PBL
MPAR: Development and Evaluation of Meteorological Models Used in Air Quality (cont.) • A source of important verification and developmental data for emerging Computational Fluid Dynamics (CFD) and Large Eddy Simulation (LES) models • Valuable observations for data assimilation, in particular, for EPA retrospective, high resolution AQ assessment modeling (e.g., Houston area, or WTC disaster).
MPAR: Direct Uses in Air Quality Modeling and Assessment • Toxic plume or wild fire smoke tracking in real-time • High-resolution 3-D wind fields for direct input to EPA endorsed plume and puff models, which currently diagnose wind fields from point observations or models. • Uses in trajectory modeling/analysis and source attribution studies • Potential to derive physical characteristics of aerosols in the PBL • Enhance US EPA emission inventories, in particular, wild fire emissions
