Evaluation of ISC3, AERMOD, and ADMS Dispersion Models with Observations from Five Field Sites
EVALUATION OF THE ADMS, AERMOD, AND ISC3 DISPERSION MODELS WITH THE OPTEX, DUKE FOREST, KINCAID, INDIANAPOLIS, AND LOVETT FIELD DATA SETS Steven R. Hanna*, Bruce A. Egan**, John Purdum***, and Jen Wagler**** *CSI MS 5C3, George Mason Univ., Fairfax, VA 22030-4444 USA **Egan Environmental, 75 Lothrop St., Beverly, MA 01915 USA ***17 Peters Way, North Attleboro, MA 02760 USA ****URS Greiner Woodward-Clyde, 38 Chauncy St., Boston, MA 02111 USA ABSTRACT The model evaluation exercise addresses the question whether the new models, ADMS and AERMOD, produce improvements over ISC3 when compared with a range of field observations. ADMS and AERMOD have similar state-of-the-art scientific components, whereas ISC3 contains 1960s technology. The five sets of field observations used in the statistical evaluation represent a cross-section of typical scenarios encountered by modelers. The OPTEX data base concerns non-buoyant tracer releases within an oil refinery complex, and the Duke Forest data base involves non-buoyant tracer releases from area and volume sources in an open field. The Kincaid, Indianapolis, and Lovett data bases all deal with buoyant plumes from tall stacks at power plants. However, the settings are quite different, since the Kincaid plant is surrounded by flat farmland, the Indianapolis plant is located in an urban environment, and the Lovett plant is sited in a valley surrounded by complex terrain with monitors at elevations higher than the stack. Analysis of the model performance measures suggest that ISC3 typically overpredicts, has a scatter of about a factor of three, and has about 33% of its predictions within a factor of two of observations. -
HYSPLIT User's Guide
HYSPLIT User's Guide Last Revised: April 2020 HYSPLIT USER's GUIDE Roland Draxler Barbara Stunder Glenn Rolph Ariel Stein Albion Taylor Version 5 - Last Revision: April 20201 TABLE OF CONTENTS Abstract The HYSPLIT (Hybrid Single-Particle Lagrangian Integrated Trajectory) Model installation, configuration, and operating procedures are reviewed. Examples are given for setting up the model for trajectory and concentration simulations, graphical displays, and creating publication quality illustrations. The model requires specially preformatted meteorological data. Programs that can be used to create the model's meteorological input data are described. The User's Guide has been restructured so that the section titles match the GUI help menu tabs. Although this guide is designed to support the PC and UNIX versions of the program, the executable of the on-line web version is identical. The only differences are the options available through the interface. Features The HYsplit (HYbrid Single-Particle Lagrangian Integrated Trajectory) model is a complete system for computing trajectories complex dispersion and deposition simulations using either puff or particle approaches.2 It consists of a modular library structure with main programs for each primary application: trajectories and air concentrations. Gridded meteorological data, on a latitude-longitude grid or one of three conformal (Polar, Lambert, Mercator) map projections, are required at regular time intervals. The input data are interpolated to an internal sub-grid centered to reduce memory requirements and increase computational speed. Calculations may be performed sequentially or concurrently on multiple meteorological grids, usually specified from fine to coarse resolution. Air concentration calculations require the definition of the pollutant's emissions and physical characteristics (if deposition is required). -
