   The 22^nd of June 2015, a new version of the CALPUFF software has been released. The Version 7 of the CALPUFF modeling system contains many new features. The model updates introduce new source types including roadways and flare modeling. The new pre-processor SURFGEN which can process sub-hourly ASOS data and the post-processors CALRANK, CALAVE and CALMAX are also now available.

   This version 7 includes all the new features introduced in Version 6 (which is now being deprecated), such as the ISORROPIA (now updated to v2.2) inorganic gas-particle equilibrium model, aqueous phase chemistry and an anthropogenic secondary organic aerosol (SOA) module based on the CMAQ/MADRID model; options to use sub-hourly time steps for both meteorological and emissions data, nested grid capabilities; an option in CALPOST to compute daily peak one-hour concentration values consistent with the new U.S. 1-hour SO2 and NO2 standards.
