MACC supports HIPPO-III campaign

hippo2.jpgMACC supports the American HIPPO observational campaign by providing near-real-time forecasts of carbon monoxide, ozone, and aerosol. The “Collaborative Research: HIAPER Pole-to-Pole Observations (HIPPO) of Carbon Cycle and Greenhouse Gases Study” will measure cross sections of atmospheric concentrations approximately pole-to-pole, from the surface to the tropopause, five times during different seasons over a three year period. A comprehensive suite of atmospheric trace gases pertinent to understanding the Carbon Cycle will be measured. HIPPO missions transect the mid-Pacific ocean and return either over the Eastern Pacific, or over the Western Atlantic. The programme will provide the first comprehensive, global survey of atmospheric trace gases, covering the full troposphere in all seasons and multiple years.
