Description

Full mission name: Chemistry of the Atmosphere: Field Experiment over the Pacific

Description:

The CAFE-Pacific mission was the third in a triad of measurement campaigns with the HALO aircraft to investigate tropical tropospheric oxidant photochemistry in combination with aerosol particle formation and growth under clean, pristine conditions over land, and contrast the results with those in marine and polluted conditions. HALO has been uniquely equipped with a custom designed payload by three departments of the MPIC and partner institutes. It consists of highly sensitive mass spectrometric and optical instrumentation, to comprehensively characterize atmospheric oxidation mechanisms, as well as their control of particle production and growth throughout the troposphere; from reactive radicals to large volatile organic compounds and their reaction products, and from small clusters to stable aerosol particles. The tropical region is of particular relevance on Earth because it represents a large fraction of the troposphere where oxidation processes are most efficient, and directly connects to the stratosphere through the upward motion generated by the formation of deep convective clouds. For example, about 80 to 90 percent of atmospheric methane oxidation takes place in the tropics, even though the largest fraction is emitted at higher latitudes. The tropical troposphere is referred to as the wash room of the atmosphere. Moreover, tropical atmospheric chemistry and aerosol processes have been much less studied compared to the extra-tropics.
