Measurements of atmospheric aerosol backscatter coefficients, using a coherent CO/sub 2/ lidar at 9.25- and 10.6-..mu..m wavelengths, are described. Vertical profiles of the volume backscatter coefficient ..beta.. have been measured to a 10-km altitude over the Pasadena, Calif., region. These measurements indicate a wide range of variability in ..beta.. both in and above the local boundary layer. Certain profiles also indicate a significant enhancement in ..beta.. at the 9.25-..mu..m wavelength compared with ..beta.. at the 10.6-..mu..m wavelength, which possibly indicates a major contribution to the volume backscatter from ammonium sulfate aerosol particles.
