1. A method of determining the humidity and temperature of atmospheric air at selected distances along a field of view in atmospheric air by passive IR spectrometry, comprising:

  • (1) providing an IR spectrometer disposed in atmospheric air;

    (2) measuring the values of a plurality of IR power densities received by the spectrometer along a single field of view at a plurality of at least five discrete, selected IR wavelengths;

    (3) providing a set of equations which equate the measured IR power density to functions of temperature and humidity at the selected wavelengths; and

    (4) calculating 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 using approximated values of temperature and humidity along the field of view.
