Outgoing radiation consists of Refected solar radiation plus the Terrestrial infrared radiation. Net radiation is measured as watts per square meter. Temperature is measured in degrees celcius and relative humidity in percent. The Wind Sentry Anemometer and Vane measure horizontal wind speed and wind direction. The anemometer cup rotation produces an AC voltage signal with a frequency directly proportional to wind speed.
Wind speed is measured in meters per second.
Wind vane position is transmitted by a precision conductive plastic potentiometer. The output signal is an analog voltage directly proportional to the wind direction azimuth angle. The Tipping Bucket Rain Gauge is an adaptation of the standard Weather Service tipping bucket rain Gauge. Output is a switch closure for each bucket tip. A multiplier in the datalogger program determines the units in which rainfall is reported.
