Description:

***BEIS3 is now embedded in the CMAQ model***

The Biogenic Emissions Inventory System, Version 3 (BEIS3) is being developed to support the needs of regional and urban-scale air quality simulation models. BEIS3 is designed to be incorporated into the Sparse Matrix Operational Kernel Emissions (SMOKE) system, which serves as the emissions processor for most EPA atmospheric pollutant models. BEIS3 computes gridded, hourly emissions for speciated volatile organic compounds (VOCs) and nitric oxide from biogenic sources. BEIS3 requires, as meteorological inputs, data files on solar radiation and air temperature. The Biogenic Landuse Database, Version 3 (BELD3) provides vegetation data needed to perform these calculations. BELD3 is available for the United States at a 1-km resolution.

The model was developed by George Pouliot/Ellen Kinnee (Dynamac Corp.) and Jeff Vukovich (MCNC).

Model Inputs :More complex model with greater input requirements, but no substantial modular or sub-model components.

Model Outputs :BEIS3 creates a hourly, gridded emissions file in IO/API format that is input to air quality models such as the Community Multiscale Air Quality (CMAQ) modeling system. For further information on CMAQ, click here

Model Computer Requirements:

Model Operating Systems Needs :Unix/Linus/Windows

Model Hardware Needs :No minimum requirements

Model Programming Language(s) :The internal GIS capabilities assumes that vegetation data have been "pre"-gridded.

ARC/INFO is usually used to generate gridded vegetation data files.

Meteorological data must be processed and gridded, usually performed with a met processor embedded in the Models-3/CMAQ system.

The model uses Biogenic Emissions Landuse Database (Version 3).
