Abstract

The impact of aerosols on cloud macrophysical (cloud extent, cloud thickness and liquid water path), cloud microphysical (droplet and ice crystals concentrations and size distributions), and precipitation has received a great deal of attention for over 50 years. The pioneering work of Gunn and Phillips (1957), Squires (1958), Squires and Twomey (1961), Warner (1968) and Warner and Twomey (1967), to mention just a few, pointed out that high concentrations of cloud condensation nuclei (CCN) from anthropogenic sources, such as from industrial pollution and from burning of sugarcane, can increase cloud droplet number concentration (CDNC), hence increasing cloud microphysical stability and potentially reducing precipitation efficiency. Although the connection between increased CCN and increased CDNC has been supported by many in situ observations, the impact of CCN on precipitation is less well established.
