Black carbon impacts the albedo of snow by absorbing a higher proportion of solar radiation leading to higher melt rates in snow and the development of a water resource shortage during summer months in the PNW. For this reason, the measurement of black carbon in the Cascades of Washington is an important, but under-measured property. Through sampling on Mount Rainier and analysis using the LAHM instrument, the concentration of black carbon was measured on 13 different occasions at five separate locations on Mount Rainier. After analysis the BC concentrations were overlaid with forest fire smoke trajectories to determine increased snow exposure to smoke vastly increases BC concentrations.
