Snow Gauge

A snow gauge is a meteorological instrument used to record the depth of snowfall at a specific location.

Meteorology is the scientific study of the atmosphere that focuses on weather processes and forecasting. ...

The snow gauge consists of two parts, a copper catchment container and the funnel shaped gauge itself. The actual gauge is mounted on a pipe outdoors and is approximately 1.5 m (4 ft 11 in) high, while the container is 51.5 cm (201/4 in) long. General Name, Symbol, Number copper, Cu, 29 Chemical series transition metals Group, Period, Block 11, 4, d Appearance metallic brown Atomic mass 63. ... For the term related to television programmes, see watershed (television). ...

When snow has fallen the container is removed and replaced with a spare. The snow is then melted, while still in the container, and poured into a glass measuring graduate. While the depth of snow is normally measured in centimetres, the measurement of melted snow (water equivalent) is in millimetres. An estimate of the snow depth can be obtained by multiplying the water equivalent by ten. For other uses, see Snow (disambiguation). ... cm redirects here, alternate uses: cm (disambiguation) A centimetre (symbol cm; American spelling: centimeter) is an SI unit of length. ... A millimetre (American spelling: millimeter), symbol mm is an SI unit of length that is equal to one thousandth of a metre. ...

The snow gauge suffers from the same problem as that of the rain gauge when conditions are windy. If the wind is strong enough, then the snow may be blown across the wind gauge and the amount of snow fallen will be under-reported. However, due to the shape and size of the funnel this is a minor problem.

If the wind is very strong and a blizzard occurs then extra snow may be blown into the gauge and the amount of snow fallen will be over-reported. In this case the observer must judge how much of the water is from snow blown into the container and how much is fallen snow.

Another problem that occurs, is when both snow and rain fall before the observer has time to change the gauge. In all of these cases the observer must judge how much of the water is snow and how much is rain. Rain falling For other uses see Rain (disambiguation). ...

Remote reading gauges, such as used by weather stations, work similarly to rain gauges. They have a large catch area (such as a drum sawn in half, top to bottom) which collects snow until a given weight is collected. When this critical weight is reached, it tips and empties the snow catch. This dumping trips a switch, sending a signal. The collection then repeats. If the catch container has a heater in it, it measures the snow weight accurately. It is also possible to tip based on volume instead of weight, with apropriate fill sensing.

Another snow sensor called a snow pillow looks like a round bag laying on the ground. Inside the pillow is a liquid such as an environmentally safe antifreeze. Usually the snow pillow will be connected to a manometer. The manometer reading will vary based on how much snow is sitting on the pillow. This type of sensor works well for many locations but is more difficult to use in areas of hard blowing snow. A manometer is a pressure measuring instrument, often also called pressure gauge. ...

Snow Gauge (153 words)
The Snow Gauge uses dark blue for high contrast in the snow yet able to blend into normal surroundings.
The Snow Gauge panel is then slid down the legs to contact the ground.
As the snow piles up around the gauge, the last number showing at the bottom of the Snow Gauge is the accumulated snow fall amount.
Meteorology - MSN Encarta (1081 words)
Precipitation is measured by a rain gauge or a snow gauge.
A rain gauge consists of an upright cylinder, open at the top to catch the rain and calibrated either in millimetres or in inches, so that the total depth of the precipitated water may be measured.
The snow gauge also is a cylinder, which is thrust into the snow to collect a core of snow.
