The Fused Air Quality Surface Using Downscaling (FAQSD) Files is derived from data on Ozone (O3) and Particulate Matter 2.5 (PM2.5). The data provides predictions for national-scale annual average concentration of O3 (μg/m3) and PM2.5 (μg/m3) in the United States using monitoring data and Community Multiscale Air Quality (CMAQ) output.
