Impact/Purpose:
The objectives of this task are to continuously develop and improve the Community Multiscale Air Quality (CMAQ) modeling system, which is the science implementation within the Models-3 system framework for air quality simulation. CMAQ is a multiscale and multi-pollutant chemistry-transport model (CTM) that includes the necessary critical science process modules for atmospheric transport, deposition, cloud mixing, emissions, gas- and aqueous-phase chemical transformation processes, and aerosol dynamics and chemistry. It relies on Models-3 I/O API to support machine independent data access and maintains simple interfaces among science processor modules to provide a high-level of modularity.
Description:
The SMOKE Tool is a part of the Models-3 system, a flexible software system designed to simplify the development and use of air quality models and other environmental decision support tools. The SMOKE Tool is an input processor for SMOKE, (Sparse Matrix Operator Kernel Emission system) the air emission modeling component of Version 4.1 of Models-3. The SMOKE Tool provides emission file in the correct format, creates gridded files of emission data, and performs quality control and analysis of emission data for SMOKE. SMOKE Tool may be operated either within the graphical user interface of Models-3 system, or independently in a "stand-alone" mode. SMOKE Tool is made available with a set of standard EPA emission inventories for the years 1990, 1995, and 1996 as well as economic projection factors and temporal and spatial allocation data. This document provides detailed descriptions of the software structure, related file formats and assumptions, environment variable settings, and other details for the use of SMOKE Tool. SMOKE Tool and this document are available from the Models-3 web site at http://www.epa.gov/asmdnerl/models3/.
