Measurements of both horizontal gradients and vertical profiles of aerosols, cloud droplets and thermodynamic parameters
in the cloud topped marine boundary layer off of central California are presented. They suggest that, while aerosols
can indeed modulate cloud albedo, other parameters such as sea surface temperature may similarly affect cloud albedo.
Additionally, the impact of aerosols, through sedimentation and precipitation, on cloud optical depths and thus albedo
is not always in accord with conventional expectations and can either enhance or decrease the albedo, depending on
ambient conditions. Taken together, these results suggest that current estimates of indirect forcing by aerosols could be
significantly in error.
