Mesonet Senors and Measurements information

An aerovane at the standard height of 33 feet (10 meters) measures wind direction, speed, and gust.

A platinum resistance thermometer in a fan-aspirated radiation shield at a height of 33 feet (10 meters) measures air temperature. The difference between this and air temperautre at 80 inches (2 m) is the standard for inversion monitoring.

A platinum resistance thermometer in a fan-aspirated radiation shield at a standard height of 80 inches (2 meters) measures air temperature.

A hygrometer in a passive radiation shield at a standard height of 80 inches (2 m) measures relative humidity.

A heated thermopile pyranometer measures global horizontal irradiance. This is used in the calculation of evapotranspiration (crop water use).

A barometer at a height of 60 inches (1.5 meters) measures station pressure. This is used to calculate altimeter setting which removes the effect of elevation.

A temperature-corrected sonic sensor measures snow depth.

A weighing gauge with heated rim in an Alter shield at a standard height of 60 inches (1.5 meters) measures liquid, freezing, and frozen precipitation.

A thermistor at a depth of 4 inches (10 centimeters) measures bare soil temperature. This is the standard for agricultural weather.

Five time-domain reflectometers at the standard depths of 2, 4, 8, 20, and 40 inches (5, 10, 20, 50, and 100 centimeters) measure soil water content and temperature under natural cover.

Two 180° cameras facing southwest and northeast image the sky.

An aerovane at the non-standard height of 10 feet (3 meters) measures wind direction, speed, and gust. Wind speed and gust will generally be less compared to the standard of 33 feet (10 meters).

Two thermistors in passive radiation shields at non-standard heights of 40 inches and 10 feet (1 and 3 meters) measure air temperature. The difference is used for inversion monitoring. Magnitudes will generally be of the same sign but lower magnitude compared to the standard 33 feet and 80 inches (10 and 2 meters).

A thermohygrometer in a passive radiation shield measures temperature and relative humidity at a standard height of 80 inches (2 m).

A heated silicon-cell pyranometer measures global horizontal irradiance. This is used in the calculation of evapotranspiration (crop water use).

A barometer at a height of 60 inches (1.5 meters) is used to measure station pressure. This is used to calculate pressure corrected for elevation (altimeter setting).

A unheated tipping bucket gauge at a standard height of 40 inches (1 meter) measures non-freezing, liquid precipitation.

A thermistor at a depth of 4 inches (10 centimeters) measures bare soil temperature. This is the standard for agricultural weather.

Five coaxial impedence dielectric reflectometers at the standard depths of 2, 4, 8, 20, and 40 inches (5, 10, 20, 50, and 100 centimeters) measure soil water content and temperature under natural cover.

An anemometer at the non-standard height of 10 feet (3 meters) measures wind speed and gust. Wind speed and gust will generally be less compared to the standard of 33 feet (10 meters).

A vane at the non-standard height of 10 feet (3 meters) measures wind direction.

A thermohygrometer in a passive radiation shield measures temperature and relative humidity at a standard height of 80 inches (2 m).

A silicon-cell pyranometer measures global horizontal irradiance. This is used in the calculation of evapotranspiration (crop water use).

A unheated tipping bucket gauge at a standard height of 40 inches (1 meter) measures non-freezing, liquid precipitation.
