what aerosols and are indirect effects modeled?
The distributions of marine, desertic, urban aerosols, sulfate aerosols are specified. Marine and desertic aerosols are constant in all experiments. Urban aerosols vary according to estimates between 1850 and 2000. Sulfate aerosols are specified in all experiments according to Boucher and Pham (2002) data, see http://www-loa.univ-lille1.fr/~boucher/sres/ for more details. Note that only the direct effect of anthropogenic sulfate aerosols was taken into account. D. dynamic vegetation? No E. ice-sheets?
