Eddy Covariance High-Frequency Data for Urban and Suburban Sites in Indianapolis, Indianapolis (US-INc, US-INg)

As part of the Indianapolis Flux (INFLUX) project two tall towers (US-INc and US-INg) were deployed to measure heterogeneous urban landscapes. Instruments for these tall towers are mounted on communication towers. US-INc measured fluxes over a developed downtown region of Indianapolis. US-INg measured fluxes from a suburban neighborhood to the west and a highway to the east.

The time spans for these data sets are US-INc: November 2020 to November 2023 and US-INg: April 2019 to November 2023. The data files will be updated approximately yearly for those sites still in operation. These data are .ghg files containing thirty-minute periods of the 10Hz measurements from the sonic anemometer and infrared gas analyzer. Note that fluxes were additionally measured from a suburban neighborhood to the south and a highway to the north for January 2013 to November 2013, (US-INf) but 10Hz data are not available.
