Abstract
A sensing system and method suitable for use in humidity sensing instruments such as radiosondes to determine the true relative humidity of the atmosphere contemporaneously with other parameters at the same altitude as the radiosonde rises or descends. The indicated relative humidity of the air contiguous with a humidity sensing element and the temperature of the humidity sensor and the surrounding air temperature, remote from the sensor, are measured. The true relative humidity of the surrounding air is determined by the product of the indicated relative humidity and the ratio of the saturated vapor pressure at the sensor temperature to that at the surrounding air temperature.
