Chemical, Optical, and Microphysical Measurements of In-situ Troposphere

Extending the success of the SMART mobile facility, COMMIT was built in 2006 as the companion in-situ observatory for studying basic chemical, optical and microphysical properties of atmospheric aerosols and trace gases. Like SMART, all COMMIT instruments are integrated in a twenty-foot weather-sealed trailer with thermostatic temperature control. The mobile laboratories can be deployed and operated together or individually. COMMIT has now been an integral part of multiple field campaigns, including 7SEAS/BASELInE (2010-13), Asian Monsoon Years (2008-12), NAMMA (2006), and BASE-ASIA (2006).
