Figure 6.3: The normalised
radiative forcing for sulphate aerosol from the intercomparison study of Boucher
et al. (1998). A log-normal distribution with a geometric mean diameter of 0.170
µm and a geometric standard deviation of 1.105 together with an aerosol
optical depth of 0.20 at 0.55 µm and a Lambertian surface reflectance of
0.15 was assumed. For details of the acronyms and the radiation codes used in
the calculations see Boucher et al. (1998).
