    Colorado State University radiation instrumentation and data reduction procedures for the Convail 990 during summer MONEX
    (Colorado State University. Libraries, 1980) Ackerman, Steven A., author; Cox, Stephen K., author; Department of Atmospheric Science, Colorado State University, publisher
    Describes the basic system design and the radiative instrumentation maintained by Colorado State University on board the Convail 990 jet aircraft during the Summer Monsoon Experiment (MONEX). Discusses calibration procedures and gives the derived constraints used to convert instrument output to engineering units. Also discusses specific problems encountered during data reduction and the methods used to overcome them.

    Radiative characteristics of soil derived aerosols
    (Colorado State University. Libraries, 1987-07) Ackerman, Steven A., author; Cox, Stephen K., author
    A multiple scattering model is employed to study the impact of a dust layer on the radiative fluxes at the top of the atmosphere, at the bottom of the atmosphere and within the atmosphere. The sensitivity of the radiative fluxes to various changes in the optical properties of the dust is assessed. Model calculations of the radiative fluxes , with environmental conditions as input, are compared to the aircraft measured fluxes. A parameterization of the extinction coefficient, the single scattering albedo and the asymmetry parameter for a dust layer in the SW spectral region is presented which accounts for the physical and chemical changes of a dust layer as it is mobilized and transported. It is demonstrated that the parameterization scheme is applicable to other aerosols, including water clouds. A scaling parameter is presented which can be used to describe the optical properties of an aerosol layer with a large effective size parameter. The parameterization of the LW radiative properties of the dust layer follows the classic emissivity approach. The effective emissivity is derived for a non-isothermal layer. The radiative parameterizations are incorporated into a radiative-convective equilibrium climate model to assess the impact of the dust microphysical properties on the steady state temperature.
