Modelling the spatial variability of maximum mountain snow depth in Northern Norway

Nordia Geographical Publications, 2016
Snow depth is highly variant in wind-dominant mountain environments. The variation is especially high at local scales. Winter maximum snow depth influences the ground temperatures and the beginning of the growing season.

Long‐Term Variability and Spatial Differentiation of the Frost‐Free Period in Iceland

International Journal of Climatology, EarlyView.
Warming in Iceland (May–September) is expressed as fewer Tmin < 0°C days in the interior and more Tmin > 0°C days along the coasts. ABSTRACT Climate change in subarctic regions leads to significant transformations in thermal conditions; however, the long‐term variability of the frost‐free season (FFS)—and consequently, the growing period—remains poorly

Mapping snow depth in open alpine terrain from stereo satellite imagery [PDF]

, 2016
International audienceTo date, there is no definitive approach to map snow depth in mountainous areas from spaceborne sensors. Here, we examine the potential of very-high-resolution (VHR) optical stereo satellites to this purpose.

On the Snow Scale for Measuring Maximum Snow Depth

Journal of the Japanese Society of Snow and Ice, 1968
A snow scale for measuring the maximum depth of accumulated snow in remote regions was developed.The snow scale consists of a wooden pole with 10 cm aluminium pins of 3 mm in diameter driven into the pole at 10 cm intervals on both sides of the pole. The pin is bent downward by the settling force of snow when it is covered with new snow of about 10 cm ...

Deglaciation of the Burren glacio‐karst, western Ireland, during Termination 1: Implications for North Atlantic climate and karstification

Journal of Quaternary Science, EarlyView.
Abstract The Burren uplands in western Ireland form one of the most extensive and best‐preserved examples of glacio‐karst in Europe. Subsumed by the Irish ice sheet during the Late Pleistocene, granite erratic boulders and in situ silica veins in the limestone bedrock provide a rare opportunity to reconstruct the timing and rate of deglaciation ...

Investigation of radar backscattering from second-year sea ice [PDF]

The scattering properties of second-year ice were studied in an experiment at Mould Bay in April 1983. Radar backscattering measurements were made at frequencies of 5.2, 9.6, 13.6, and 16.6 GHz for vertical polarization, horizontal polarization and cross

Estimation of Sea Ice Thickness Distributions through the Combination of Snow Depth and Satellite Laser Altimetry Data [PDF]

, 2009
Combinations of sea ice freeboard and snow depth measurements from satellite data have the potential to provide a means to derive global sea ice thickness values. However, large differences in spatial coverage and resolution between the measurements lead

Application of Low-Cost UASs and Digital Photogrammetry for High-Resolution Snow Depth Mapping in the Arctic [PDF]

, 2017
The repeat acquisition of high-resolution snow depth measurements has important research and civil applications in the Arctic. Currently the surveying methods for capturing the high spatial and temporal variability of the snowpack are expensive, in ...

Snow Depths Survey by Aerial Photographs

Journal of the Japanese Society of Snow and Ice, 1964
The Hokuriku region was attacked by heavy snow fall in January, 1963 and aerial photographs of the whole region were taken by the Defence Forces of Japan for providing basic data to prevent snow disasters.Using these aerial photographs, we, the staff of Geographical Survey Institute, compiled the distribution maps of snow depth on a scale of 1 : 200 ...

Development of Selective Plane Illumination Surface Enhanced Raman Scattering Spectral Microscopy for Improved Cellular Imaging

Journal of Raman Spectroscopy, EarlyView.
Selective plane illumination (SPI) is combined with SERS spectral imaging to reduce background, improve image contrast, and enable improved spectroscopy from molecules on the surface of nanoparticles. This approach provides improved imaging and spectroscopy from nanoparticles in complex environments, such as biological cells.
