Record #123667:

Firn temperature and meltwater refreezing in the lower accumulation area of the Greenland ice sheet, Pâkitsoq, West Greenland / Roger J. Braithwaite.

Title: Firn temperature and meltwater refreezing in the lower accumulation area of the Greenland ice sheet, Pâkitsoq, West Greenland / Roger J. Braithwaite.
Author(s): Braithwaite, Roger J.
Date: 1993.
In: Grønlands Geologiske Undersøgelse. Rapport. (1993.), Vol. 159 (1993)
Abstract: Study carried out as part of EPOCH international project on sea-level changes. In this study area, at 1440 to 1620 m a.s.l., meltwater percolates several metres into firn and refreezes, warming firn by 5 to 7°C compared with annual air temperatures. Firn warming is closed related to surface melt which can be estimated by several methods. Relatively high degree-day factor is needed to account for melt rates found.
