IMPROVEMENT OF GLOBE ANEMO-RADIOMETER USING GLOBE THERMOMETERS WITH DIFFERENT DIAMETERS

Abstract

 We used globe thermometers with different diameters (4 mm and 12 mm) for Globe Anemo-radiometer(GAR) to improve the measurment accuracy of wind speed while securing that of shortwave radiation. In addition, the possibility of a novel wind speed measurement method of GAR which based on an empirical method without heat balance analysis. The combination of different diameter globe thermometers reduced the power consumption of GAR and increased the accuracy of wind speed measurement but that of shortwave radiation decreased. An empirical wind speed measurement of 4 mm globe showed usefulness.
