About the 3m Temperature Probe

Screen (left) inside which is mounted the humidity/temperature probe (right).

The temperature probe is mounted 3m above the ground on the ERU Control Room. It is an integral part of a combined Humidity/Temperature Probe.

Temperature is measured by measuring the electrical resistance of a calibrated thermistor (temperature dependent resistor), and is recorded in degrees Celsius.

The humidity/temperature probe and pyranometer are mounted together outside R111

The probe is mounted inside a radiation screen to ensure that accurate shade temperature, not direct sunlight temperature, is measured.
