An Ultra-Wideband, Microwave Radar for Measuring Snow Thickness on Sea Ice and Mapping Near-Surface Internal Layers in Polar Firn [PDF]

, 2013
Sea ice is generally covered with snow, which can vary in thickness from a few centimeters to >1 m. Snow cover acts as a thermal insulator modulating the heat exchange between the ocean and the atmosphere, and it impacts sea-ice growth rates and overall ...

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 ...

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.

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 ...

Algorithms for the snow cover depth calculation from measurements of the soil-atmosphere registering complex [PDF]

, 2018
Algorithms for the calculation of snow cover depth from measurements of the soil-atmosphere registering complex are presented. Methods for determining the air-snow interface from the temperature sensors near the soil surface are discussed.

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

Enhancing snow depth estimation with snow cover geometrical descriptors

Frontiers in Earth Science
Snow depth (SD) estimations are very valuable in particular for snow-hydrological modelling, water resource management, ecological studies, and natural hazard assessment such as avalanche forecasting. In statistical SD models, snow-covered area is often used as a source of information.

Exploitation of ERTS-1 imagery utilizing snow enhancement techniques [PDF]

Photogeological analysis of ERTS-simulation and ERTS-1 imagery of snowcovered terrain within the ERAP Feather River site and within the New England (ERTS) test area provided new fracture detail which does not appear on available geological maps ...

Snow Depth on Arctic Sea Ice

Journal of Climate, 1999
Snow depth and density were measured at Soviet drifting stations on multiyear Arctic sea ice. Measurements were made daily at fixed stakes at the weather station and once- or thrice-monthly at 10-m intervals on a line beginning about 500 m from the station buildings and extending outward an additional 500 or 1000 m.

Snowex 2017 Community Snow Depth Measurements: A Quality-Controlled, Georeferenced Product [PDF]

Snow depth was one of the core ground measurements required to validate remotely-sensed data collected during SnowEx Year 1, which occurred in Colorado. The use of a single, common protocol was fundamental to produce a community reference dataset of high
