HIGHLIGHTS

  • Natural and Anthropogenic Aerosols impact on Glaciers.
  • No specific trend yet more work is needed.
  • Changing AODS over years at Borders.
  • Need for this kind of work over Glaciers.

ABSTRACT


The snowpack in the Sierra Nevada mountain range is the primary source of water for California. Many studies have shown that the increase in aerosols could lead to a reduction of the snowpack in this region. This study focuses on evaluating changes in the snowpack during the winter and summer seasons from 2000 till 2016 and determining the relationship between aerosols and the retreat of glaciers in the Sierra Nevada.The change detection analysis has shown reductions of 76.4% and 91.4% in the snowpack during winter and summer, respectively. Utilizing the aerosol optical depth (AOD), Angstrom exponent, snow depth anomalies, snowfall, radiation fluxes, and albedo, the effect of aerosols on snowfall over the Sierra Nevada glaciers has been examined for this 17-year period. Overall, based on correlation analysis, a negative relationship exists between the AOD and the snowfall.
