Run CALMET in Parallel with CALPUFF View
One limitation of the CALPUFF air dispersion model is that it can only be executed on a single processor (i.e., serially). Previous modeling tips have discussed ways around this limitation. For example, executing CALPUFF with a single source will run faster than attempting to model multiple sources at a time. Modelers can then employ CALSUM to assess cumulative impacts. This approach has the added benefit of providing a way to assess individual source contributions.

CALPUFF & CALPUFF View: What’s the Difference?
Lakes Software recently announced its acquisition of the CALPUFF modeling system from Exponent. Because Lakes’ CALPUFF View interface is well known throughout the modeling community, some modelers were not aware of the differences between this application and the stand-alone modeling system. This tip will explain the relationship between the modeling system and the CALPUFF View interface.

AERSCREEN View - Modeling Fumigation
AERSCREEN is the U.S. EPA’s recommended screening model based on AERMOD. Designed to produce estimates of “worst-case” hourly concentrations for a single source, AERSCREEN is intended to produce concentration estimates that are equal to or greater than those produced by AERMOD with the degree of conservatism varying by project.
