The earth's climate exhibits tightly interwoven processes covering vast scales in time and space. Clouds in particular play a vital role, by removing pollutants, and by acting as pistons in the atmospheric heat engine. However, the extraordinary complexity of clouds has meant that their exact role in the earth's climate, and how climate will change, largely remains a mystery. Is the problem fundamentally simple or impossibly complex? A small group I lead is trying to tease from clouds their importance to various atmospheric chemical, dynamic and radiative processes.

*Really just Assoc. Prof., but nephology is a wonderful, though neglected 19th century word meaning "the study of clouds"
