The effects of aerosols and particles suspended in the atmosphere on the radiative properties of clouds have been difficult to quantitate; direct measurements are scarce, and the different effects involved are not readily isolated. Kaufman and Fraser (p. 1636) analyzed satellite data over South America to establish the dependence of climate forcing by smoke particles from biomass burning on the availability of water vapor. The results indicate that smoke increases cloud reflectance and allow an estimate of climate forcing by smoke clouds to be made.
