Puff Air Dispersion Model
CALPUFF View provides a complete graphical solution for the CALPUFF modeling system: CALPUFF,
CALMET, CALPOST, and their related pre- and post-processors. Supports USEPA Approved Version 5.8,
Version 6, and Version 7.
CALPUFF is recommended for a wide range of complex environments where steady-state models fall short.
CALPUFF is a multi-layer, multi-species non-steady-state puff dispersion model which simulates the effects of time-and space-varying meteorological conditions on pollution transport, transformation, and removal.
Far-field impacts (beyond 50km) which cannot be modeled with traditional plume models like AERMOD.
Three-dimensionally varying meteorological field makes it useful for regions with very complex terrain.
CALPUFF View’s features make it easy to execute the entire suite of pre- and post-processors.
Impeccably designed to streamline all aspects of model setup, execution, and analysis.
Utilize multiple CPU cores to significantly accelerate computational speed, processing large datasets efficiently and reducing simulation time.
Automatically download and import high-resolution satellite and street map imagery directly into your projects for precise source placement.
Play and record dynamic plume animations highlighting pollutant dispersion over time in sync with wind patterns.
Export buildings, sources, receptors, and pollutant contours into an immersive 3D environment for better decision-making.
Analyze how pollutant plumes travel and disperse across specific terrains with intuitive overlays on satellite imagery.
Automated download for NED, SRTM, and USGS DEM data ensures flexibility and accuracy in your environmental modeling.
Runs SMERGE, METSCAN, READ62, PXTRACT, and PMERGE. Download files automatically from WebMET.
Complete 3D visualization of sources, buildings, wind field, and results in context with terrain.
Step-by-step graphical Wizards ensure you never miss required information during model setup.
Unified tools for drawing, running, and automated contouring/posting of results.
Automatically create building tiers to simulate sloped roofs for accurate downwash modeling.
Ready-to-use professional templates with company logos and project specific information.
Included with every software license.
