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.

  The 8th meeting of the group dealing with the revision of the EN 13725 took place in Amsterdam at the begining of June. Some important issues have being discussed.

   This time the list of participants was not as large as in previous meeting. Just 15 people met in Amsterdam. However the list of actions approved was really high, as 23 actions were taken.
