This is the AmeriFlux version of the carbon flux data for the site US-MWW Allegan Wetland. Site Description - Privately owned and managed wetland along the Rabbit River, a tributary to the Kalamazoo River. Land owner controls water level at site. Sensors are at the edge of open water and emergent vegetation, with wet forests surrounding the wetland. Site was chosen to represent managed wetlands along the Kalamazoo River watershed.

This is the AmeriFlux version of the carbon flux data for the site US-TrB Trout Bog. Site Description - Trout Bog is part of the North Temperate Lakes Long Term Ecological Research Network described here: https://lter.limnology.wisc.edu/researchsite/trout-bog
This is the AmeriFlux version of the carbon flux data for the site CA-DB2 Delta Burns Bog 2. Site Description - The Burns Bog Ecological Conservancy Area (BBECA) in the metro Vancouver area presents a unique opportunity for insight into greenhouse gas dynamics post restoration. The bog was significantly disturbed for peat mining, development and agriculture over the last century, however since 2005 there has been both active restoration and natural regeneration occurring within the bog. Hence areas of bog are at varying stages of ecological recovery. This site is a Pine-Sphagnum low shrub site characteristic of a later successional stage. Conversely, CA-DBB, another AmeriFlux site in BBECA, is a Beakrush-Sphagnum site characteristic of an earlier successional stage.
This is the AmeriFlux version of the carbon flux data for the site US-HWB USDA ARS Pasture Sytems and Watershed Management Research Unit- Hawbecker Site. Site Description - Hawbecker farm is owned by Penn State University. The farming that took place was performed by their Farm Operations Division. The ground is rolling terrain, next to wooded areas, the Beef and Sheep Reasearch Farm, The University Airport, and other large fields maintained by Farm Operations. At the time of this collection period, the site housed another Meteorological Site, a Phenocam, and the GraceNet plots. Crop Rotation during period was 2 years Alfalfa, 1 year Corn for grain and 1 year Wheat.
This is the AmeriFlux version of the carbon flux data for the site US-DFK Dairy Forage Research Center - Kernza. Site Description - Crop field (10 acres) in annual and perennial rotation. Alfalfa (2015-2018), intermediate wheatgrass grown for Kernza grain and grass forage (planted September 2019-2023, terminated spring 2024), corn silage (2024), planted in winter wheat (late summer/fall 2024). Winter wheat (2025) followed by alfalfa (to be planted August 2025).
This is the AmeriFlux version of the carbon flux data for the site US-MH2 Huntley, Montana irrigated barley site 2. Site Description - flood-irrigated barley field
This is the AmeriFlux version of the carbon flux data for the site US-TrS Trout Lake Area South Sparkling Bog. Site Description - South Sparkling Bog was plowed after snow events during the winter of 2019/20 as an experimental treatment with Trout Bog (US-TrB) as a control
This is the AmeriFlux version of the carbon flux data for the site US-Tur Turner Ranch. Site Description - Pasture
This is the AmeriFlux version of the carbon flux data for the site US-Wwt Willamette Wheat. Site Description - The site was established in summer 2014 and is part of the Oregon eddy covariance flux tower network . Meteorological variables such as temperature, humidity, solar irradiance and wind are measured at this site. Turbulent fluxes of water vapor, carbon dioxide and heat are observed and stored as 30 minute averages. The crop changes periodically and rye grass and fescue is grown alternately at this site located in Oregon's Willamette Valley with its relatively mild climate. The Wheat site is also part of the PhenoCam network operated by Harvard University and the University of New Hampshire.
This is the AmeriFlux version of the carbon flux data for the site CR-Fsc Filadelfia sugar cane cropland. Site Description - The research site is located in a sugar cane cropland generally harvested in December. Sugarcane is irrigated(furrow irrigation) sporadically only during the dry season (January-April).Crop height varies from 0m to 4m.
This is the AmeriFlux version of the carbon flux data for the site MX-Ray Rayon, monsoon subtropical shrubland. Site Description - Precipitation during the NAM season (July–September) is approximately 76% of the annual total at the site (Vivoni, Rodríguez, et al., 2010) leading to a peak in vegetation greenness in the month of August (Méndez‐Barroso et al., 2009). Site vegetation is composed of drought‐deciduous trees and shrubs, including torote papelío (Jatropha cordata), tree ocotillo (Fouquieria macdougalii), acacia (Acacia cochliacantha), palo verde (Parkinsonia praecox), Mexican mimosa (Mimosa distachya), and velvet mesquite (Prosopis velutina) as well as organpipe cactus (Stenocereus thurberi).
This is the AmeriFlux version of the carbon flux data for the site US-MC2 Creston, Montana pivot-irrigated spring wheat 2. Site Description - pivot-irrigated spring wheat
This is the AmeriFlux version of the carbon flux data for the site US-MVF Montana Vaughn Fallow. Site Description - spring wheat
This is the AmeriFlux version of the carbon flux data for the site US-MVW Montana Vaughn Wheat. Site Description - spring wheat
This is the AmeriFlux version of the carbon flux data for the site US-Act Acton Lake Flux Tower Site. Site Description - This tower is located at Acton Lake, a eutrophic reservoir immediately surrounded by forest but draining an agricultural watershed in Hueston Woods State Park outside of Oxford, OH. The EC instrumentation was originally deployed 25 m from shore on a dock piling. In April of 2018 a lake tower was installed >200 m from the closest shoreline. The EC instrumentation was deployed on this aquatic tower on 7 May 2018.
This is the AmeriFlux version of the carbon flux data for the site US-Bsg Burns Sagebrush. Site Description - The site was established in 2012 and is part of a NOAA observation network for high precision measurements of carbon dioxide concentrations. It is located about 60 km southwest of Burns, Oregon in the Oregon High Desert. The vegetation in this area is dominated by sagebrush. The sampling inlets are at the heights of 18.5, 28.5, and 38.5 m. Gas analysis is performed with a Picarro 2302 Cavity Ringdown Spectrometer and a Li-Cor 7200 enclosed path IRGA. The tower is also equipped with a set of meteorological instruments, including an HMP sensor, radiation sensors (incoming and diffuse PAR, Net radiometer), and a CSAT3 sonic anemometer. This site is also part of the PhenoCam network operated by Harvard University and the University of New Hampshire.
