Tower at which greenhouse gases are measured as part of the Indianapolis Flux Expriment (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.)
