Honesty note: CAMS separates dust (desert surface class) from smoke/haze aloft (high AOD, low dust) reliably. Which desert or whose fire is seasonal inference only — Saharan-typical May–Sep on the coast; West Texas dust when only Lubbock/Midland/Abilene are dusty; Mexico ag-fire smoke typical Apr–Jun; Canadian wildfire smoke typical Jul–Sep. We never claim more than that.
