Pacific Oxidants, Sulfur, Ice, Dehydration, and cONvection Experiment (POSIDON)

Pacific Oxidants, Sulfur, Ice, Dehydration, and cONvection Experiment (POSIDON) — The NASA POSIDON project took place in Guam in the fall of 2016 and focused on the chemistry, cirrus clouds, and dehydration of the tropical upper troposphere and lower staratosphere in the Western Pacific.  SPEC instrumented the NASA WB-57 with a CPI, FCDP, and 2D-S to investigate the microphysical properties of anvil cirrus detrained from deep convection as well as thin cirrus near the tropopause.
