  • 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...

  • Effects of aerosols on the properties of deep convective clouds

    Creator:
    Brown, Daniel A.
    Abstract:
    Aerosols are tiny particles that serve as nuclei for cloud droplet and ice crystal formation. Increases in aerosol concentration lead to clouds with smaller but more numerous droplets. Some recent studies have found evidence that ice crystal size in deep convective clouds is also reduced by elevated aerosol concentrations. In...
