  • Effects of solar heating on the indirect effect of aerosols as deduced from observations of ship tracks

    Creator:
    Christensen, Matthew W.
    Abstract:
    One kilometer Moderate Resolution Imaging Spectroradiometer (MODIS) observations for Terra (morning) and Aqua (afternoon) satellites were used to follow the morning to afternoon evolution of marine stratocumulus clouds that were affected by ship stack exhaust. The observations covered the summer months of 2002-2003 and August 2007 for marine layers off...

  • Response of marine stratus to successive polluting events by ships

    Creator:
    Sechrist, B.
    Abstract:
    Ship tracks have proven to be an ideal laboratory for studying the response of marine stratocumulus to an increase in aerosol pollution. Here the response of already polluted marine stratocumulus to further pollution was examined by studying the clouds where two ship tracks cross. 78 crossings of ship tracks were...

  • Using ship tracks to characterize the effects of haze on cloud properties

    Creator:
    Segrin, Matthew S.
    Abstract:
    1-km MODIS observations of ship tracks off the west coast of the U.S. are used to characterize changes in cloud visible optical depths, cloud droplet radii, cloud cover fraction, and column cloud liquid water amount as low-level marine clouds respond to particle pollution from underlying ships. This study re-examines the...
