Abstract

Researchers at Brigham Young University (BYU) have developed a software framework for modeling dust emission and transport using the Community Multiscale Air Quality (CMAQ) modeling system in conjunction with the Weather Research and Forecasting (WRF) model and other utility programs. This framework uses meteorological data, land use data, and soil properties to predict dust concentrations for a specified area. This User Guide describes the start-to-finish process required to install and utilize relevant software to calculate and visualize dust concentrations. Note that the examples and figures provided in the guide are specific to Utah in the western United States, where this research was conducted, but the same modeling process is applicable to any domain within the contiguous USA. Changes to certain input files may extend the applicability of this process to other global regions, but those changes are not covered here. This guide is intended to provide instructions on how to run a dust simulation using specific versions of CMAQ and WRF; it is not a comprehensive review of the CMAQ dust model or WRF meteorological model and does not provide insight into the relevance or accuracy of dust emission results.
