Web8 Apr 2024 · A Solent sonic anemometer measured sensible heat fluxes (not latent) and the ablation rate of intercepted snow was measured using the weighed tree. The ablation rate was converted to equivalent energy units(flux) as if all the energy was consumed for phase change to vapor (a reasonable assumption given the -15 to -1 °C air temperatures). Web11 Apr 2024 · Dust and black carbon (BC) can darken snow and ice surface and play pivotal roles in glacier mass loss. Thus, a quantitative assessment of their contributions to glacier summer melting is critical.

WebSnow ablation rate is the ablation needed to remove the snow-pit accumulation by the observation date Table 3. Dates, mean elevation and standard deviation of satellite … WebThe flow of alpine glaciers is primarily controlled by the slope of the land beneath the ice (Figure 16.10). In the zone of accumulation, the rate of snowfall is greater than the rate of melting. In other words, not all of the snow that falls each winter melts during the following summer, and the ice surface is always covered with snow.

WebFor both treatments, we measured with a dedicated snow tribometer the friction coefficient µ on compacted snow at different temperatures (−10 °C; −5 °C; −3 °C) for a gliding speed range between 1 and 6.1 ms −1. We compared the obtained µ values with those of untreated AISI 301H plates and of stone grinded, waxed UHMWPE plates.
