MARC recordA 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. |
