Abstract

The column aerosol particle number and low cloud microphysical parameters derived from AVHRR remote sensing are compared over ocean for four months in 1990. There is a positive correlation between cloud optical thickness andaerosol number concentration, whereas the effective particle radius has a negative correlation with aerosol number. The cloud liquid water path (LWP), on the other hand, tends to be constant with no large dependence on aerosol number. This result contrasts with results from recent model simulationswhich imply that there is a strong positive feedback between LWP and aerosol number concentration. Estimates for indirect forcing over oceans derivedfrom the satellite data/model comparison range from -0.7 to -1.7 Wm(-2).
