Seasonal Variations of Snow Depth on Mars

Science, 2001
Using topography collected over one martian year from the Mars Orbiter Laser Altimeter on the Mars Global Surveyor (MGS) spacecraft, we have measured temporal changes in the elevation of the martian surface that correlate with the seasonal cycle of carbon dioxide exchange between the surface and atmosphere.

Global Snow Depth Climatology

1988
Abstract : This report describes the USAF Environmental Technical Applications Center's Global Snow Depth Climatic Database; tells how the database was created and how it can be updated. It also tells potential users of the Snow Depth Database how to order data.

Evaluation of Ultrasonic Snow Depth Sensors for U.S. Snow Measurements

Journal of Atmospheric and Oceanic Technology, 2008
Abstract Ultrasonic snow depth sensors are examined as a low cost, automated method to perform traditional snow measurements. In collaboration with the National Weather Service, nine sites across the United States were equipped with two manufacturers of ultrasonic depth sensors: the Campbell Scientific SR-50 and the Judd Communications ...

Snow depth controls palsa growth

Permafrost and Periglacial Processes, 1994
AbstractWhen a young palsa has risen sufficiently above a mire (bog) and has developed steep sides, drifting snow collects against these sides and inhibits freezing of adjacent ground. Measurement of the temperature regime on the top surface, and at the foot, of the northern edge of a 2.6 m high palsa in Utsjoki, Finland supports this hypothesis.

Interfacial Forces Between Tire and Snow Under Different Snow Depths

SAE Technical Paper Series, 2006
<div class="htmlview paragraph">All the frictional forces developed from tire-snow interfaces are closely associated with snow depth and snow sinkage. One of the important differences between tire-soil interaction and tire-snow interaction is that the latter is explicitly snow depth dependent.

Snow Depth Measurement Using Ultrasonic Sensor

Zorig Melong | A Technical Journal of Science, Engineering and Technology, 2017
Snow measurements are essential for studying climate, predicting drought, and assessing water availability. Like other parts of the Himalayas, Bhutan's rivers are fed by glaciers and snowmelt. Scientific studies conducted in Bhutan have primarily focused on glaciers, glacial lakes, and glacial outburst floods, while their dynamics have received ...

Modeling snow depth extremes in Austria

Natural Hazards, 2018
Maps of extreme snow depths are important for structural design and general risk assessment in mountainous countries like Austria. The smooth modeling approach is commonly accepted to provide more accurate margins than max-stable processes. In contrast, max-stable models allow for risk estimation due to explicitly available spatial extremal ...

Injuries from single-vehicle crashes and snow depth

Accident Analysis & Prevention, 1988
Swedish official statistics on road traffic accidents shows a remarkable variability among different winter seasons in single-vehicle crashes resulting in personal injuries--one of the major causes of personal injury in road traffic. This study presents results from analyses investigating the role played by snow as an injury-reducing factor.

Map of Snow Depth in Norway

Norsk Geografisk Tidsskrift - Norwegian Journal of Geography, 1972
This paper explains the method of compiling the map of snow depth in Norway, based not only on data of meteorological stations lying mainly at the bottom of valleys, but also on measurements of snow accumulation on the glaciers. The main point in compiling this map was to analyse the dependence of snow depth on the height of localities in different ...
