• Remote Monitoring of Ozone in the Troposphere Using Earth Reflected Differential Absorption

      Guagliardo, John L.; Bundy, Donald H. (International Foundation for Telemetering, 1974-10)
      A method of remotely monitoring the tropospheric concentration of ozone is proposed. The method uses two lasers, each emitting a different wavelength. It is shown that even though only two laser wavelengths are used, the method is both specific and accurate for oz.one concentrations which are encountered in most urban areas.
