Still the fastest emissions processing tool available. SMOKEv2.4 introduces new approaches for simulating air toxics, a new version of the BEIS model, and support for detailed simulations of the emissions from airports.

New In SMOKEv2.4		SMOKE News
Hazardous Air Pollutants (HAPs) support SMOKEv2.4 includes several enhancements to support the simulation of emissions sources of toxic pollutants. Inventory Import Smkinven has an improved version of the SMKINVEN_FORMULA option that supports multiple formulas. Updated Smkinven now can read pollutant names up to 16 characters to support Chemical Abstracts Services (CAS) codes. The enhancement allows for HAPs to be included in day-specific (PTDAY) and hour-specific (PTHOUR) emission inventories. Speciation Enhanced Spcmat to skip applying a speciation cross-reference entry for sources with zero emissions. Updated Spcmat to correctly handle the applicaion of ROG to TOG conversions for multiple pollutants (e.g., both VOC and NONHAPVOC). Growth and Controls Enhanced Cntlmat to detect whether controls factors from a given packet were applied to an inventory before it was input to SMOKE. Updated Grwinven to correctly write out the CEFF, RPEN, or REFF values to an IDA or ORL projected inventory file. BEIS Version 3.13 Biogenic Emission Inventory System (BEIS) model version 3.13 is integrated in SMOKEv2.4 for generating gridded, hourly emissions in a format consistent for air quality modeling. BEIS 3.13 revises the parameterizations that account for the effects of leaf temperature and solar radiation on emissions.		SMOKE version 2.4 release The Institute for the Environment, in cooperation with the U.S. EPA, is pleased to announce the release of SMOKE version 2.4 SMOKEv2.4 includes enhancements and bug fixes relative to SMOKEv2.3.4. SMOKEv2.4 integrates the latest Biogenic Emission Inventory System (BEIS) model version 3.13 for generating gridded, hourly emissions in a format consistent for air quality modeling. SMOKEv2.4 is also now compatible with the Federal Aviation Administration (FAA)'s Emission Modeling and Dispersion Modeling System (EDMS) used to estimate emissions from airports. See the release notes and documentation for SMOKEv2.4 for additional information. Special SMOKE Training for Environment Canada CMAS trainers held a special training session at the CMAS Center offices in March, 2007 to teach SMOKE to emissions modelers from Environment Canada.
