The latest site to join ARM’s set of fixed-location atomspheric observatories began operations in September 2013. Identified as the Eastern North Atlantic (ENA), this facility is located on Graciosa Island in the Azores. The Azores are an island group located in the northeastern Atlantic Ocean, a region characterized by marine stratocumulus clouds. Response of these low clouds to changes in atmospheric greenhouse gases and aerosols is a major source of uncertainty in global climate models.
The islands experience a tepid, oceanic, subtropical climate with mild temperatures ranging anywhere from 59 °F to 80 °F. Light clothes with one or two sweaters/jackets are enough to survive the cooler nights, winter season and occasional rain showers.
