By: T. Baisden; M. Norris; T. Bromley; A. Zondervan; G. Brailsford; E. D. Keller; J. C. Turnbull

Description: National Isotope Centre, GNS Science, Lower Hutt, New Zealand. We use the Kapuni Gas Treatment Plant to examine methodologies for atmospheric monitoring of point source fossil fuel CO2 (CO2ff) emissions. The Kapuni plant, located in rural New Zealand, removes CO2 from locally extracted natural gas and vents that CO2 to the atmosphere, at a rate of ~0.1 Tg carbon per year. The plant is located in a rural dairy ...

Description: Department of Atmospheric Science, Pusan National University, Korea. Most previous evaluations of satellite performance relied on pair wise comparisons with limited spatial and temporal coverage of surface-based measurements such as soundings and in-situ measurements. Especially, validation of satellite HCHO measurements is very difficult because ground-based HCHO measurements are extremely sparse. We use a new scientific approach, statistical analyses wit...
