Gordon, J I

During the contract period, new methods for obtaining absorption, aerosol and total-scattering optical thickness, and single-scattering albedo from tropospheric visible spectrum data were published and then used on two extant sets of tropospheric optical data in the visible spectrum. One ground-based set of measurements predated heavy atmospheric pollution. The other set of airborne measurements was from a metropolitan area containing pollution sources. Application of the methods to these data sets further developed the methods, provided substantial examples of their use, served to update the data, and provided a means to access all the atmospheric optical data measured prior to 1976. A significant finding was that the aerosol-scattering optical thickness of the total atmosphere or of separate haze layers can be described by a modified Angstrom equation in which the constant is a function of the power of the wavelength.
