CONCEPTIntroduction
The new CONCEPT (CONsolidated Community Emissions Processing Tool) Emissions Processor is now available for use by the emissions modeling community. Developed as joint project between Alpine Geophysics, LLC and ENVIRON Corporation, with Midwest RPO and joint RPO funding, the CONCEPT model combines the best attributes of current emissions modeling systems into an open source model.
CONCEPTGoals
Open SourcePublic domain software
• POSTgres, POSTGis, perlGPL CompliantUsers encouraged to customize and shareCode and documentation available at:
conceptmodel.org
CONCEPTGoals
TransparentDatabase Structure easy to understandSelf-documenting tables and naming conventionsExtremely well documented code
CONCEPTGoals
Quality ControlMultiple levels of QA analysis Interim products maintained to facilitate QAEasy review of calculation procedures and assumptionsMultiple debug and report levels

Spatial AllocationSurrogates applied at Country, state, county, tribal and/or SCC level
CONCEPTArea Source Model
Tribal EmissionsExplicitly coded to accept tribal emissions independently of any state or county identifiersExtracts and corrects double counted emissions when both tribal-level and county-level are reported.Spatial allocation includes tribal spatial overlays for correct spatial distribution
