RISA Stochastic Methodology for Regional Wind-Field Modeling
Publisher: American Meteorological Society
Abstract: Three-dimensional, regional scale (≈1000 km) air-quality simulation models require hourly inputs of U and V wind components for each vertical layer of the model and for each grid cell in the horizontal. The standard North ...
New Categorical Metrics for Air Quality Model Evaluation
Publisher: American Meteorological Society
Abstract: Traditional categorical metrics used in model evaluations are ?clear cut? measures in that the model?s ability to predict an ?exceedance? is defined by a fixed threshold concentration and the metrics are defined by ...
Sensitivity of Regional Oxidant Model Predictions to Prognostic and Diagnostic Meteorological Fields
Publisher: American Meteorological Society
Abstract: Objective analysis and diagnostic methods are used to provide hourly meteorological fields to many air quality simulation models. The viability of using predictions from the Pennsylvania State University?National Center ...
Linking the Eta Model with the Community Multiscale Air Quality (CMAQ) Modeling System to Build a National Air Quality Forecasting System
Publisher: American Meteorological Society
Abstract: NOAA and the U.S. Environmental Protection Agency (EPA) have developed a national air quality forecasting (AQF) system that is based on numerical models for meteorology, emissions, and chemistry. The AQF system generates ...
