Abstract:

Data are presented on the construction of an airborne hygrometer. The basic measurement of the instrument is the radiation absorption in an infrared wavelength region of high water vaporABSORPTION AS COMPARED TO THAT OF A NEARBY REFERENCE WAVELENGTH OF NEGLIGIBLE WATER OR OTHER CONTAMINANT ABSORPTION. The optical null measure of absorption is converted and corrected in an analog computer first to a measure of total water, equivalent to vapor pressure, then an output reading of outside dew point temperature.
