In Situ Reflectance Spectra of Glacier Facies

Reflectance spectra (Hemispherical Directional Reflectance, HDR) were collected during two field campaigns from the full range of facies available on end-of-melt-season glaciers. In August 2010, data were collected on Midtre Lovénbreen. In August 2011, data were collected on the major western outlet of Langjökull. These two locations were chosen so as to include sampling of glaciers that had undergone different accumulation and melting histories. Additional differences were introduced by the springtime eruption of Grímsvötn, which deposited windborne ash on Langjökull’s surface. All spectra were measured with an ASD FieldSpec Pro on loan from the UK’s Natural Environment Research Council’s Field Spectroscopy Facility (FSF).
