"Shallow cumulus, such as those found in the trade-winds of the North Atlantic, are perhaps the predominant cloud type on the planet. They might also be the simplest. Surprisingly large gaps in our understanding of these clouds still remain. For instance, how might they change in response to global warming? Or how do their properties depend on perturbations to the atmospheric aerosol? Because shallow cumulus play a key role in modulating the flux of radiant energy to the surface ocean, as well as the rate of evaporation of water into the atmosphere these questions are central to our understanding of the climate system, and our ability to predict climate change.
The site, which has been in operation since April 1st, 201,0 is located on the east coast of the island of Barbados, on a site called Deebles Point, where it is exposed to the relatively undisturbed easterly (trade) winds." (MPI-Met)
