Short summary
The atmospheric seasonal impact of dust and biomass burning is considered for the western United States from 1999 to 2014. Median contributions to spring and summer aerosol optical depth (AOD) from dust and biomass-burning aerosols are comparable, with more frequent and short duration high AOD measurements due to biomass-burning episodes in summer than in spring. This data set highlights the wide scale implications of a warmer, drier climate on visibility in the western US.
