Desert dust emitted from the greater Colorado Plateau and deposited onto the Colorado Mountain system has increas ed in frequency and intens ity over recent decades . The consequent dust - induced reductions in snow albedo are affecting Colorado snowmelt hydro graphs by accelerating snowmelt rates, when dust is exposed at or near the snowcover surface. A combination of dust intensity per storm, depth of dust layers, and spring weather patterns affect how dust influences the change in spring snowmelt and runoff p at terns. These factors can be used to calculate melt forcing from dust, and this information can be used regionally to improve runoff forecasting.
