Measurement of temperature and humidity
The air temperature and the relative humidity are measured with a combined sensor. The sensor is housed in an instrument shelter (Gill) for protection against direct sunlight. The shelter and the sensor are installed at a height of 15 m above the institute's roof. Calibration is carried out by comparative measurements using a hand-operated aspiration psychrometer.
