Puff Tracking Animations in Google Earth™  

Using the export to Google Earth feature, you can quickly and easily see where your puff will impact.  The play feature shows how your puff disperses over time.

Auto-Download of Terrain/Land Use Data

CALPUFF View allows the user to automatically download global terrain data files (DEM, SRTM, GTOPO) and land use data (LULC, NLCD92, GLCC).  Easily process data for anywhere in the world.

Sloped Roof Tool

This utility allows users to automatically create multiple building tiers based on the defined top and bottom tier to create the appearance of a sloped roof.

CALPUFF View Easy-to-Use Wizards 

CALPUFF View provides an easy-to-use graphical interface.  Each section can be completed by following the steps outlined in various wizards so that you don’t miss specifying required information.

Complete Meteorological Pre-Processors

CALPUFF View seamlessly runs SMERGE, METSCAN, READ62, PXTRACT, and PMERGE for all of your met processing.   Surface, Upper Air, and Precipitation files can be downloaded automatically from WebMET for US locations only.

Parallel CALMET 

Increase your processing capability! CALPUFF View can utilize multiple cores when running the CALMET model.

Support for Latest EPA Approved Models 

You can select to use either the US EPA approved CALPUFF models or the latest version of the CALPUFF models.  The user can switch from one model to another with the click of a button, even in the middle of a project!
