| Abstract | As part of the Indianapolis Flux (INFLUX) project three flux towers (US-INa, US-INb, US-BWa) were deployed to monitor turfgrass lawns and two flux towers (US-BWb, US-BWc) to monitor pasture. Each tower was of short stature, standing roughly three meters above the ground. Lawns are an abundant vegetative community in urban areas and are frequently managed through irrigation, fertilization, or mowing. US-INa measured fluxes over a cemetery lawn with lower intensity management (i.e., infrequent mowing, no fertilization, and no irrigation). US-INb measured fluxes over a golf course (i.e., frequent mowing, fertilization, and irrigation). US-BWa measured fluxes over a lawn on the National Institute for Standards and Technology campus. The lawn is considered lower intensity management (i.e., infrequent mowing, no fertilization, and no irrigation). The US-BWb and US-BWc towers measured fluxes at Montgomery County’s compost facility with landcover type of pasture/grasslands. US-BWb was located in a pasture grass field (infrequently mowed) south of the compost facility. US-BWc was located directly beside the southern edge of the compost facility.
The time span for these data sets are US-INa: August 2017 to April 2019, US-INb: November 2018 to April 2019, US-BWa: January 2021 to November 2023, US-BWb: June 2022 to November 2023, and US-BWc: June 2023 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. For more information on the sites, visit
