  2. Snow gauge - Wikipedia

    en.wikipedia.org/wiki/Snow_gauge

    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.

    Rain gauge for measuring liquid precipitation over a set period of time; Wind sock for measuring general wind speed and wind direction; Wind vane (also called a weather vane or a weathercock) for showing the wind direction; Present Weather/Precipitation Identification Sensor for identifying falling precipitation; Disdrometer for measuring drop ...

  4. Precipitation - Wikipedia

    en.wikipedia.org/wiki/Precipitation

    The corresponding English unit used is usually inches. In Australia before metrication, rainfall was also measured in "points", each of which was defined as one-hundredth of an inch. [15] Solid precipitation A snow gauge is usually used to measure the amount of solid precipitation. Snowfall is usually measured in centimeters by letting snow ...

  5. Snow - Wikipedia

    en.wikipedia.org/wiki/Snow

    The liquid equivalent of snowfall may be evaluated using a snow gauge [31] or with a standard rain gauge, adjusted for winter by removal of a funnel and inner cylinder. [32] Both types of gauges melt the accumulated snow and report the amount of water collected. [33]

  6. Meteorological instrumentation - Wikipedia

    en.wikipedia.org/wiki/Meteorological_instrumentation

    The first devices used to measure weather phenomena were the rain gauge, the anemometer and the hygrometer. The 17th century saw the development of the barometer and the Galileo thermometer while the 18th century saw the development of the thermometer with the Fahrenheit and Celsius scales.

  8. Snow science - Wikipedia

    en.wikipedia.org/wiki/Snow_science

    Snow density (ρ s) is the mass per unit volume of snow of a known volume, calculated as kg/m 3. Classification runs from very fine at below 0.2 mm to very coarse (2.0–5.0 mm) and beyond. Snow hardness (R) is the resistance to penetration of an object into snow. Most snow studies use a fist or fingers for softer snows (very soft through ...

  9. Present weather sensor - Wikipedia

    en.wikipedia.org/wiki/Present_weather_sensor

    The present weather sensor (PWS) is a component of an automatic weather station that detects the presence of hydrometeors and determines their type (rain, snow, drizzle, etc.) and intensity. It works on a principle similar to a bistatic radar , noting the passage of droplets, or flakes, between a transmitter and a sensor.
