 CALPUFF Training Course – 2015
Scottsdale, Arizona | April 2015
About CALPUFF Version 7 Ongoing CALPUFF model enhancements provide new capabilities for simulating flares and road‐source emissions, and all source‐types with sub‐hourly variations in emissions and meteorological conditions. Roadways can now be simulated with an elongated puff method that is consistent with the reference method of using many adjacent volume sources, but has significantly reduced run‐times so that large areas can be readily modeled. Flare simulations use meteorologically‐aware variable emissions files from the Alberta Flare Analysis program, so that flame‐tip properties including position can be tracked. New features in CALMET include an interface to sub‐hourly ASOS and WRF/MM5 meteorological datasets. The 2‐minute average ASOS data are read by the new SURFGEN processor and formatted as a CALMET‐ready, sub‐hourly SURF.DAT file. Flexible post‐processing capabilities address new assessment requirements. Running‐averages as well as block‐averages can be produced, and reported for any number of user‐specified ranks. Important updates have been made to the chemical transformation modules, including the ISORROPIA v2.2 aerosol module, modified gas phase chemistry and aqueous phase oxidation of SO2, and SOA formation. CALApps Software Package CALApps , a new Windows OS 64‐bit compatible graphical user interface, provides a flexible streamlined experience to constructing simulations and it introduces an expanded set of analysis tools to explore model inputs and results. Each of the major processors offers the user both a GUI and INP tab (which remain fully consistent with each other), providing the user with convenient data‐entry methods while still allowing access to the full control file: The included Viewer (driven by Golden Software’s Surfer) allows the user the ability to plot and animate wind vectors, temperature, precipitation, mixing height and stability as well as concentration contours over terrain and land‐use: The CALApps software package also features a large number of utilities such as a program that allows users to view vertical profiles of temperature, wind speed or wind direction from an UP.DAT file or another that lets users view and animate puff tracks over terrain: ‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐ (888) 656‐EXPO www.exponent.com [email protected]
