Why, When, and Where?

Low marine boundary layer clouds over the ocean exert a large influence on Earth’s climate through reflection of sunlight and mediating interactions between air and sea.

These clouds are a challenge to global climate models (computer codes that attempt to describe and predict the climate), which have difficulty in accurately representing them and the transitions among their different types (stratocumulus, cumulus, etc.).

MAGIC will study these clouds by deploying radars and other scientific instrumentation on the Horizon container ships Reliance and Spirit making regular transects between Los Angeles and Hawaii from October, 2012 to September, 2013.

The primary objective is to improve the representation of the stratocumulus-to-cumulus transition, an ever-present phenomenon along this particular transect, in climate models.
