The Determination of the Snow Optical Grain Diameter and Snowmelt Area on the Greenland Ice Sheet Using Spaceborne Optical Observations
Vandecrux, Baptiste; Box, Jason E.; Wehrlé, Adrien; Kokhanovsky, Alexander A.; Picard, Ghislain; Niwano, Masashi; Hörhold, Maria; Faber, Anne-Katrine; Steen-Larsen, Hans Christian (Journal article; Peer reviewed, 2022)The optical diameter of the surface snow grains impacts the amount of energy absorbed by the surface and therefore the onset and magnitude of surface melt. Snow grains respond to surface heating through grain metamorphism ... -
Exploring the role of snow metamorphism on the isotopic composition of the surface snow at EastGRIP
Harris Stuart, Romilly; Faber, Anne-Katrine; Wahl, Sonja; Hörhold, Maria; Kipfstuhl, Sepp; Vasskog, Kristian; Behrens, Melanie; Zuhr, Alexandra M.; Steen-Larsen, Hans Christian (Journal article; Peer reviewed, 2023)Stable water isotopes from polar ice cores are invaluable high-resolution climate proxy records. Recent studies have aimed to improve our understanding of how the climate signal is stored in the stable water isotope record ... -
Local-scale deposition of surface snow on the Greenland ice sheet
Zuhr, Alexandra M.; Münch, Thomas; Steen-Larsen, Hans Christian; Hörhold, Maria; Laepple, Thomas (Journal article; Peer reviewed, 2021)Ice cores from polar ice sheets and glaciers are an important climate archive. Snow layers, consecutively deposited and buried, contain climatic information from the time of their formation. However, particularly ... -
Quantifying the Stable Water Isotopologue Exchange Between the Snow Surface and Lower Atmosphere by Direct Flux Measurements
Wahl, Sonja; Steen-Larsen, Hans Christian; Reuder, Joachim; Hörhold, Maria (Journal article; Peer reviewed, 2021)Surface processes in high latitudes play an important role in global climate and thus understanding the physics of these systems is critical for improving climate projections. The characterization of the stable water ... -
The role of sublimation as a driver of climate signals in the water isotope content of surface snow: Laboratory and field experimental results
Hughes, Abigail G.; Wahl, Sonja; Jones, Tyler R.; Zuhr, Alexandra; Hörhold, Maria; White, James W. C.; Steen-Larsen, Hans Christian (Journal article; Peer reviewed, 2021)Ice core water isotope records from Greenland and Antarctica are a valuable proxy for paleoclimate reconstruction, yet the processes influencing the climate signal stored in the isotopic composition of the snow are being ... -
A Snapshot on the Buildup of the Stable Water Isotopic Signal in the Upper Snowpack at EastGRIP on the Greenland Ice Sheet
Zuhr, Alexandra M.; Wahl, Sonja; Steen-Larsen, Hans Christian; Hörhold, Maria; Meyer, Hanno; Laepple, Thomas (Journal article; Peer reviewed, 2023)The stable water isotopic composition in firn and ice cores provides valuable information on past climatic conditions. Because of uneven accumulation and post-depositional modifications on local spatial scales up to hundreds ...
