Pyranometer for measuring solar radiation; 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 ...
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.
In 1662, Sir Christopher Wren invented the mechanical, self-emptying, tipping bucket rain gauge. In 1714, Gabriel Fahrenheit creates a reliable scale for measuring temperature with a mercury-type thermometer. [2] In 1742, Anders Celsius, a Swedish astronomer, proposed the 'centigrade' temperature scale, the predecessor of the current Celsius ...
Basic SNOTEL sites have a pressure sensing snow pillow, storage precipitation gauge, and air temperature sensor. However, they can accommodate 64 channels of data and will accept analog and parallel or serial digital sensors. On-site microprocessors provide functions such as computing daily maximum, minimum, and average temperature information ...
Stevenson screens may also be known as a cotton region shelter, an instrument shelter, a thermometer shelter, a thermoscreen, or a thermometer screen. Its purpose is to provide a standardised environment in which to measure temperature, humidity, dewpoint, and atmospheric pressure. It is white in color to reflect direct solar radiation.
On Saturday, high temperatures in Portland got up to 85 F, breaking the daily record temperature of 83 F set back in 2014 by two degrees. The warmth over the next day will be a noticeable ...
The clock is ticking for families hoping to send letters to Santa Claus at the North Pole this holiday season.. Letters need to be postmarked by Monday, a spokesperson for the U. S. Postal Service ...
When measuring snowfall on a snowboard, the snowfall is measured to the nearest 0.1 in (0.25 cm). [2] The snow may be measured as often as necessary during a 6-hour period in order to record the greatest depth on the board, since snow may both accumulate and melt during the same 6-hour period. [ 5 ]
