In 2008, the second ARM Mobile Facility (AMF2) was developed to extend the capabilities of the original AMF (AMF1) deployed in 2005. The AMF2 is portable, modular, and suited for operations on oceangoing ships and in harsh environments. The AMF2 has improved data flow and communications (primarily wireless) and optimized operating procedures.
AMF2 instrument capabilities include standard meteorological instrumentation, a broadband and spectral radiometer suite, and remote sensing instruments. This instrumentation provides researchers with data from climate regimes not previously explored. The AMF2 also has available space, power, and data processing capabilities for additional instruments brought by guest scientists. For more information, see the AMF2 Baseline Instruments page.
The first AMF2 deployment, during the winter of 2010-2011 and at an elevation of 6,700 feet, was in the clouds (no need for measurements from aircraft) at Steamboat Springs, Colorado. The objective was to gather information about liquid and mixed-phase clouds.
The second deployment, on Gan Island in the Maldives (a small island chain in the Indian Ocean), ran until early 2012. The focus of the Gan study was the Madden-Julian Oscillation, a large tropical weather system that recurs every 30-60 days, starting in the Indian Ocean. The oscillation distributes heat and energy into the atmosphere until it dissipates in the middle of the Pacific Ocean.
The third AMF2 deployment was a year-long series of shipboard voyages across the Pacific Ocean, from Los Angeles to Honolulu, to study cloud transformations above the ocean.
