Air trajectories and snowfall over Alaska–Yukon icefields: implications for ice-core accumulation studies
Zdanowicz, Christian
Glaciers surrounding the Gulf of Alaska contain records of past climate. However, interpreting records from the region’s interior vs maritime mountain ranges is challenging, partly due to uncertainties in air transport associated with snowfall. Here, we combine in situ snow accumulation data and back trajectory modeling to examine air-parcel trajectories associated with snowfall in the St. Elias and Alaska Ranges, and their implications for climate records contained in glacier ice. We find that
