Following a six-month land-based campaign in the Maldives to study tropical convective clouds, the Department of Energy’s second Atmospheric Radiation Measurement (ARM) mobile facility, called AMF2, is being readied for its first marine-based research campaign aboard a cargo container ship in the Pacific Ocean.
The container pictured here, owned and operated by Argonne National Laboratory, is called the "AOS Van"; it will be deployed along with the Operations Van on the Bridge Deck of the Horizon Spirit for a year. It houses numerous sensors and systems that measure aerosols in order to help determine cloud properties. The stack located at the center of the container pulls air inside, where the samples are sent to various sensors. Other sensors are located on the roof because of the limited space on the bridge deck.
