Record #104391:

A simple energy-balance model to calculate ice ablation at the margin of the Greenland ice sheet / Roger J. Braithwaite, Ole Oleson.

Title: A simple energy-balance model to calculate ice ablation at the margin of the Greenland ice sheet / Roger J. Braithwaite, Ole Oleson.
Author(s): Braithwaite, Roger J.
Oleson, Ole.
Date: 1990.
In: Journal of Glaciology. (1990.), Vol. 36(123) (1990)
Abstract: Data for daily ice ablation on Nordbogletscher (1979-83) and Qamanârssûp sermia (1980-86) are used to test model which calculates ablation from climatic data. Mean errors are small: larger for Qamanârssûp sermia, which may be due to variations in ice albedo,, but model also underestimates ablation during Föhn events. Model suggests radiation accounts for 2/3 mean ablation for June-August at both sites, while turbulent fluxes account for 1/3. Average ablation rate is higher at Qamanârssûp sermia than at Nordbogletscher because both sensible-heat flux and short-wave radiation are higher.
