Evaluation of MODIS Albedo Product over Ice Caps in Iceland and Impact of Volcanic Eruptions on Their Albedo

Gascoin, Simon; Guðmundsson, Sverrir; Adalgeirsdottir, Gudfinna; Pálsson, Finnur; Schmidt, Louise; Berthier, Etienne; Björnsson, Helgi (MDPI AG, 2017-04-25)

Albedo is a key variable in the response of glaciers to climate. In Iceland, large albedo variations of the ice caps may be caused by the deposition of volcanic ash (tephra). Sparse in situ measurements are insufficient to characterize the spatial ...
The importance of accurate glacier albedo for estimates of surface mass balance on Vatnajökull: evaluating the surface energy budget in a regional climate model with automatic weather station observations

Schmidt, Louise Steffensen; Adalgeirsdottir, Gudfinna; Guðmundsson, Sverrir; Langen, Peter L.; Pálsson, Finnur; Mottram, Ruth; Gascoin, Simon; Björnsson, Helgi (Copernicus GmbH, 2017-07-14)

A simulation of the surface climate of Vatnajökull ice cap, Iceland, carried out with the regional climate model HIRHAM5 for the period 1980–2014, is used to estimate the evolution of the glacier surface mass balance (SMB). This simulation uses a new ...
