Abstract

Temperature-induced humidity errors in the carbon humidity element ML-476 are described. The dominant error is caused by solar irradiation and results in a lowering of reported humidity values. The effect was found with both the military AN/AMT-12 and weather Bureau radiosondes. Flight studies indicate that a significant improvement in data acquisition will result from a blackening of the sensor channel walls.

Abstract

Efforts are described involving the development of an expendable, balloon-borne dew point hygrometer which is compatible with standard radiosonde equipment, maintains the inherent accuracy of this sensing technique, and as far as is possible reduces the cost. Presented here are both laboratory and field test data on a selected number of flights, together with a description of the device and its operation.
