1 Importance of Low-Clouds for Climate
Imperative that we understand the processes controlling the formation, maintenance and dissipation of low clouds in order to improve their representation in climate models.

2 Can drizzle affect MBL dynamics?

3 Precipitation and its effects on albedo
Cloud albedo strongly dependent upon open/closed cells Strong precipitation associated with open cell structure Open cells form in clear marine environment – potential anthropogenic impacts Open Cells Closed Cells Satellite Low albedo 100 km High albedo Strong drizzle Ship Radar Weak drizzle

4 Conceptual model of POC formation
Closed cells Open cells
