Post-Wildfire Black Carbon Deposition On The Snowpack In The Cascade Range, Washington State: Temporal And Spatial Variability With Implications For Accelerated Melt, Ted Uecker
All Master's Theses
Wildfires in the seasonal snow zone affect both snow accumulation and ablation patterns by decreasing forest canopy and depositing light absorbing impurities (LAI) on the snowpack. LAI such as black carbon (BC), burned woody debris, and dust reduce snow albedo (reflectance), accelerate melt, and affect the timing and availability of water resources. Charred trees in post-wildfire forests provide a significant source of BC that is deposited on the snowpack for years following a wildfire, and this effect varies with burn conditions and forest structure. Snow samples were gathered from five sites of varying burn age (0.7, 2.7, 3.8, and 9.8 …
