The INFLUX network – eddy covariance in and around an urban environment

The eddy covariance method is used by various disciplines to measure atmospheric fluxes of both vector and scalar quantities. One long-term, multi-site urban flux network experiment was the Indianapolis Flux Experiment (INFLUX), which successfully deployed and operated eddy covariance towers at eleven locations for varying deployment periods, measuring fluxes from land cover types within and surrounding the urban environment in Indianapolis, Indiana, USA. The data collected from this network of towers have been used to quantify urban greenhouse gas, energy, and momentum fluxes, assess the performance of numerical weather and carbon cycle models, and develop new analysis methods. This paper describes the available data associated with the INFLUX eddy covariance network, provides details of data processing and quality control, and outlines site attributes to assist in data interpretation.
