Tracking Public Health Impacts from Ozone and Dust in the Southwest U.S.

Thumbnail Image: 
Description: 
Many airborne contaminants exacerbate existing health problems, increase health care costs, and reduce a person’s ability to work. The Environmental Public Health Application Systems (ENPHASYS) project bridges individual and community health by forecasting atmospheric ozone, dust, and other aerosols that trigger asthmatic responses or myocardial infarction (MI). This lithograph discusses how NASA satellite data is assimilated into the Community Multiscale Air Quality Modeling System (CMAQ) and Dust REgional Atmospheric Model (DREAM) models to produce ozone, aerosol, and dust forecasts that can be used to generate relevant health-related information.
