Effects and Sensitivity of Soot-Induced Snow Albedo Change on Snowpack
The impact of soot-induced snow albedo on snow accumulation and snowpack ablation was evaluated using an energy and water balance land surface model with a newly modified snow albedo scheme. Model was tested against observed snow water equivalent (SWE) during the water year 2000 and 2002 at Ebbetts Pass site. Results show that when the soot mix ratio is 100 ng/g, the model performance is slightly improved during the snow ablation period, while snow albedo exhibits less variation. A basic sensitivity analysis indicates that snow albedo is sensitive to soot concentration in snow, and SWE is much more sensitive to soot mix ratio during the melting period, indicating the importance of accurately describing soot max ratio within snow for precisely predicting snow accumulation and snowpack ablation processes.
