  • INDOEX aerosol optical depths and radiative forcing derived from AVHRR

    Creator:
    Tahnk, William Richard
    Abstract:
    The Indian Ocean Experiment (INDOEX) had as a primary objective determining the radiative forcing due to anthropogenic aerosols over climatologically significant space and time scales: the Indian Ocean during the winter monsoon, January-March. During the winter monsoon, polluted, low-level air from the Asian subcontinent blows over the Arabian Sea and...

  • A complex signal to noise problem : determining the aerosol indirect effect from observations of ship tracks in AVHRR data

    Creator:
    Walsh, Christopher D.
    Abstract:
    Cloud reflectivity is a function of cloud liquid water content and droplet number concentration. Since cloud droplets form around pre-existing aerosol particles, cloud droplet number concentration depends on the availability of particles that can serve as cloud condensation nuclei. Given constant liquid water amount, increased availability of cloud condensation nuclei...

  • Properties of semitransparent upper-level clouds deduced from multispectral imagery data

    Creator:
    Lin, Xijian
    Abstract:
    A multispectral retrieval method is developed on the 100 km regional scale to extract the temperature, particle size, fractional cover and 11-μm emissivity of clouds which may be semitransparent in the infrared based on emitted radiances. The scheme utilizes the nonlinear relationship between emitted radiances when clouds are semitransparent and...

  • Modeling and application of multispectral oceanic sun glint observations

    Creator:
    Luderer, Gunnar
    Abstract:
    The atmospheric radiative transfer model MOCARAT was developed and is presented in this thesis. MOCARAT employs a Monte Carlo Technique for the accurate modeling of band radiances and reflectances in an atmospheric system with a ruffled ocean surface as a lower boundary. The atmospheric radiative transfer is modeled with consideration...
