Measurements of selected dicarboxylic acids in marine cloud water

Measurements of selected dicarboxylic acid concentrations in cloud water from marine stratocumulus off of the central California coast are reported. The concentrations are consistent with previously reported concentrations in marine aerosols and suggest at least a partial anthropogenic origin. The concentrations were not sufficient to impact cloud drop activation and thus provide no support for an effect on cloud albedo, though such an effect cannot be ruled out in other circumstances.
