Marine ARM GPCI Investigation of Clouds (MAGIC)
1 October 2012 - 30 September 2013
Lead Scientist: Ernie Lewis
In MAGIC, the Marine ARM (Atmospheric Radiation Measurement) GPCI Investigation of Clouds, the Second ARM Mobile Facility, AMF2, was deployed on the Horizon Lines cargo ship Spirit traversing the route between Los Angeles, CA and Honolulu, HI for one full year, from October, 2012, through September, 2013, during which the unique capabilities provided by AMF2 were utilized to observe and characterize the properties of clouds and precipitation, aerosols, and atmospheric radiation; standard meteorological and oceanographic variables; and atmospheric structure. Additionally, two Intensive Observational Periods (IOPs) were conducted January and July of 2013 during which more detailed measurements of the atmospheric structure were made.
This first marine deployment of AMF2 yielded an unparalleled and extremely rich data set that will greatly enhance the ability to understand and parameterize clouds and precipitation, aerosols, and radiation and the interactions among them; the processes that determine their properties; and factors that control these processes. Deployment of AMF2 on a ship that routinely traverses this route provided an opportunity to collect a long-term data set over a vast cloud region which is of intense interest to climate modelers. Specifically, the transect lies closely along the cross section used for the GPCI, and the data collected provided constraint, validation, and support for this modeling effort, and for associated modeling efforts such as the CGILS and EUCLIPSE. The founders of ARM recognized the importance of these marine cloud regimes and the original document recommending locales for ARM sites explicitly called for sites in the Eastern North Pacific or Eastern North Atlantic Ocean. This deployment, at long last, met the identified requirement for ARM measurements in this region.
