Tower at which greenhouse gases are measured as part of the Indianapolis Flux project (INFLUX).  INFLUX was designed to develop and evaluate methods for measurement and modeling of greenhouse gas fluxes in urban invironments.  Determination of these fluxes and their uncertainty bounds is essential for the evaluation of the effectiveness of mitigation strategies.  The current INFLUX ground-based observation network includes twelve in-situ tower-base, continuous measurements of a combination of CO₂, CO, and CH₄, in addition to a suite of other measurements, data products, and modeling efforts. INFLUX in funded by the National Insitute of Standards and Technology (NIST).  See more information.  (Photo credit: N. Miles.)

Measurement site in Round Lake , MN, at which CO2 was measured as part of the North American Carbon Program's Mid Continental Intensive (MCI).  The MCI is a test-bed for methodologies used to determine the carbon flux between land surfaces and the atmosphere.  More specifically, the overarching goal is to validate and compare regional carbon flux extimates derived from "top-down" atmospheric budgets and "bottom-up" ecosystem inventories, facilitation further  evaluation and improvement of both approaches.  The Mid-Continent Region includes Iowa and portions of surrounding states, and is largely agricultural but has significant forest cover in the northern and southern portions of the region.  For more information see NACP MCI website and RING2 website.  (Photo credit: S.

Soil plug taken within a histosol deposit of the Koyukuk National Wildlife Refuge.  Peat is an accumulation of partially decayed vegetation and usually forms in wetland conditions, where consistent flooding obstructs the flow of oxygen from the atmosphere, which slows rates of decomposition.
