Surface energy balance of the Sygyktinsky Glacier, south Eastern Siberia, during the ablation period and its sensitivity to meteorological fluctuations.

ABSTRACT: The physically based melt of the low elevation Eastern Siberian glaciers is poorly understood due to the lack of direct micrometeorological studies. We used an automatic meteorological station to record the meteorological and energy characteristics of the Sygyktinsky Glacier, south Eastern Siberia (56.8° N, 117.4° E, 2,560 m a.s.l.), during two ablation seasons and computed the surface energy balance (SEB) for 30-min intervals. The glacier ablation was both modeled and measured by stakes and a thermistor cable. The net radiation (R_net) was the main contributor (71-75 W m^-2, 89-95%) to the SEB (79 W m^-2, 100%), followed by sensible (2-4 W m^-2, 3-5%) and latent (2-3 W m^-2, 2-4%) heat fluxes. The net shortwave radiation was the main posit
