Figure

Figure 1: Cloud cover fraction (CF, solid lines) and drop effective radius (DER, broken lines) of  shallow clouds as a function of aerosol optical depth (AOD) for 4 zones over the Atlantic Ocean  during August 2002, as defined by Kaufman et al
Figure 2: A schematic illustration of the transition from non precipitating closed Benard cells to  precipitating open cells and onward to nearly complete rainout and elimination of the clouds
Figure 3: MODIS image of the relation between microstructure and dynamics of marine  stratocumulus in an area of about 400x400 km to the west of the coast of California on 26 June  2003 19:40 UT
Figure 4: Same MODIS image as in Figure 3, but for the MODIS product of effective radius at 1- 1-km resolution over a larger domain
