This is the AmeriFlux version of the carbon flux data for the site US-HBK Hubbard Brook Experimental Forest. Site Description - Mixed forest dominated by BEAL, ACRU with lesser components of PIRU. Gently sloped plateau within mountainous terrain.
This is the AmeriFlux version of the carbon flux data for the site US-KM4 KBS Marshall Farms Smooth Brome Grass (Ref). Site Description - The site was recruited to the USDA’s Conservation Reserve Program (CRP) grassland in 1987 when it was planted to smooth brome grass. The grass was cut every three years but left in place until 2009; uncut since then.

This is the AmeriFlux version of the carbon flux data for the site US-xDJ NEON Delta Junction (DEJU).
This is the AmeriFlux version of the carbon flux data for the site US-xGR NEON Great Smoky Mountains National Park, Twin Creeks (GRSM). Site Description - Great Smoky Mountains National Park straddles the ridgeline of the Great Smoky Mountains, the lower section in latitude of the Blue Ridge Mountains, which divides the larger Appalachian Mountain chain. The border between Tennessee and North Carolina runs northeast to southwest through the centerline of the park. Plants and animals common in the country's Northeast have found suitable ecological niches in the park's higher elevations, while southern species find homes in the balmier lower reaches.
This is the AmeriFlux version of the carbon flux data for the site US-xTR NEON Treehaven (TREE). Site Description - Treehaven, situated between Rhinelander and Tomahawk, WI, is one of two relocatable sites located in NEON’s Great Lakes Domain. The Treehaven property spans 1400 acres and is owned and operated by the University of Wisconsin-Stevens Point (UWSP), College of Natural Resources. UWSP uses the property and conference center for summer field techniques courses but welcomes other educators, researchers, and the public to use and enjoy their forests, trails, and facility.
This is the AmeriFlux version of the carbon flux data for the site US-KL2 KBS Lux Arbor Reserve Switchgrass. Site Description - The site was under conventional corn/soybean rotation row crop agriculture for decades before conversion. It was converted to no-till soybean in 2009 and to perennial switchgrass from 2010 onwards. Starting from 2011, the switchgrass is harvested every autumn/fall.
This is the AmeriFlux version of the carbon flux data for the site US-KL3 KBS Lux Arbor Reserve Prairie. Site Description - The site was under conventional corn/soybean rotation row crop agriculture for decades before conversion. The site was converted to no-till soybean in 2009 and to perennial native prairie from 2010 onwards. Starting from 2011, the prairie is harvested every autumn/fall.

This is the AmeriFlux version of the carbon flux data for the site US-BMM Bangtail Mountain Meadow. Site Description - montane grassland
This is the AmeriFlux version of the carbon flux data for the site US-CMW Charleston Mesquite Woodland. Site Description - Site is a riparian mesquite woodland located along an old alluvial terrace along the banks of the San Pedro River in southeastern Arizona. Site climate is semiarid with monsoonal (Jul-Sep) rainfall. The mesquite trees access groundwater from an alluvial aquifer recharged elsewhere. Site water balance is not closed and ET greatly exceeds precipitation. The understory grasses and forbs are rainfall dependent. This groundwater-dependent ecosystem is far more ebulliant and productive than the upland vegetation around it (shrublands and grasslands).
