Pre-Course Webinar: April 22, 2014 from 10:00 AM – 12:00 PM


Post-Course Webinar: May 13, 2014 from 10:00 AM – 12:00 PM


PLEASE NOTE: It is very important to register for both the pre-course as well as post-course webinars, as these are vital to the overall training program.  Please contact Sue Dilli for registration links, if needed.


The objective of this training is to provide practical hands-on training necessary to become proficient users of the CALPUFF modeling system. The trainer will use a combination of training formats including three days of in-person hands-on instruction and two on-line webinars scheduled before and after 3-day in-person training.

The course will cover the fundamentals of regulatory air dispersion modeling as well as advanced application of the CALPUFF model to address real-world air quality challenges. Attendees will be able to download and install all necessary CALPUFF software. Following the training participants will as maintain ongoing access to the software, technical support and an extensive online knowledge base. Training will include CALPUFF model theory and application to ensure that participants understand both the underlying atmospheric sciences and practical model implementation. Model theory begins with fundamental principles and builds step-by-step through state-of-the-science methods. This approach ensures users of all experience levels will benefit from attending the course. Discussion will include selection of the appropriate model and software versions based on current regulatory modeling practices and insight gained by working closely with numerous regulatory agencies across the US. Additional topics covered during the training include:

In addition to the fundamentals and underlying model and regulatory theory, attendees will complete 10 air impact modeling analysis from start to finish as part of the course. Participants will have access to modern software tools, model inputs and internet resources during the course. CALPUFF will be contrasted with other models such as AERMOD, SCIPUFF, CAMX, and CMAQ to provide participants with an understanding of the correct application of CALPUFF. For example, AERMOD is most appropriate for near-field regulatory modeling, and CALPUFF is appropriate for PSD, visibility, Class I impact analysis, or NSR studies requiring long range transport and chemistry. In addition, attendees will be alerted to all recent or anticipated EPA activities impacting the regulatory air dispersion modeling community.
