  • Properties of low-level marine clouds as deduced from advanced very high resolution radiometer satellite observations

    Creator:
    Chang, Fu-Lung
    Abstract:
    A radiation model was developed for retrieving cloud visible optical depth, droplet effective radius, and cloud top emission temperature using AVHRR satellite observations at 0.63, 3.7, and 11 μm. The model was used to determine the sensitivity of the retrieved properties to various approximations often employed in such retrievals. Droplet...

  • The spatial-scale dependence of the observed anisotropy of reflected and emitted radiation

    Creator:
    Ye, Qian
    Abstract:
    The Earth Radiation Budget Experiment (ERBE) uses Angular Dependence Models (ADMs) to convert satellite observed radiances to radiative fluxes at the top of the atmosphere. Owing to errors in scene identification and to the relationship between the spatial scales of cloud systems and the spatial resolution of the ERBE scanner,...

  • 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...

  • 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...

  • Aerosol indirect radiative forcing over the northeastern Atlantic from AVHRR observations

    Creator:
    Matheson, Mark
    Abstract:
    Advanced Very-High Resolution Radiometer 4-km data were collected over the northeast Atlantic for May-August, 1995-1999. Aerosol optical depth was retrieved in cloud-free pixels. In pixels containing clouds from only single-layered, low-level systems, a retrieval scheme that accounts for partly-cloudy pixels was used to retrieve: cloud optical depth, droplet effective radius,...
