Abstract
A method is provided for determining the humidity and temperature of atmospheric air at selected distances along a field of view by passive IR spectrometry. An IR spectrometer is provided. A plurality of IR power densities values received by the spectrometer along the field of view at a plurality of discrete, selected IR wavelengths are measured. A set of equations which equate the measured IR power density to functions of temperature and humidity at the selected wavelengths is provided. From the set of equations the temperature and humidity of the atmospheric air along the field of view at selected range segments along the field of view are calculated.
