Clouds, Aerosol and Precipitation in the Marine Boundary Layer (CAP-MBL)

1 May 2009 - 31 December 2009

Lead Scientist: Robert Wood

Observatory: AMF, GRW

The ARM Mobile Facility (AMF) was deployed in the Azores to support the Clouds, Aerosol, and Precipitation in the Marine Boundary Layer (CAP-MBL) field campaign. The AMF was located on Graciosa Island in the Azores, a Portuguese archipelago located about 3,900 kilometers from the east coast of North America. The Azores are ideally located to sample the transition from the overcast stratocumulus regime in the spring to the broken trade cumulus regime in the summer. Led by principal investigator Robert Wood, scientists involved in the campaign used data from the AMF to study processes controlling the radiative properties and microphysics of marine boundary layer clouds, a high-priority science question.

Surrounded by the Atlantic Ocean, Graciosa Island is ideal for sampling the transition from an overcast stratocumulus regime in the spring to the broken trade cumulus regime in the summer.
