Atmospheric Modeling Division, AND EPA Systems Development Center. RELEASE NOTES FOR MODELS-3 VERSION 4.1 PATCH: SMOKE TOOL AND FILE CONVERTER. U.S. Environmental Protection Agency, Washington, DC, EPA/600/R-01/076 (NTIS PB2002-101194), 2001.
Impact/Purpose:
The goal of this research is to develop and test appropriate chemical and physical mechanisms for use in EPA's Models-3 chemical/transport models. These models will be addressing issues of tropospheric photochemistry, fine particles, toxic and semi-volatile substances, and acid deposition. As such, scientifically credible mechanisms for atmospheric gas- and aqueous-phase chemistry as well as heterogeneous chemistry, applicable to the particular pollutant regimes must be included in Models-3.
Description:
This software patch to the Models-3 system corrects minor errors in the Models-3 framework, provides substantial improvements in the ASCII to I/O API format conversion of the File Converter utility, and new functionalities for the SMOKE Tool. Version 4.1 of the Models-3 system must be installed before applying this patch. The SMOKE Tool is an emission modeling component of Models-3, a flexible system designed to simplify the development and use of air quality models and other environmental decision support tools. Models-3 is designed for applications ranging from regulatory and policy analysis to understanding the complex interactions of atmospheric chemistry and physics. This document describes corrections to the Models-3 framework system, describes the procedures used by SMOKE Tool to grid spatial surrogate data, describes how additional spatial surrogate coverages may be added, and describes a new reverse gridding capability (gridded data to county or other geographic boundary data).
