This is the AmeriFlux version of the carbon flux data for the site CA-RBM Richmond Brackish Marsh. Site Description - This site is a tidal brackish marsh on the southern side of the Sturgeon Bank Wildlife Management Area (WMA) in Richmond, British Columbia, Canada. This area is situated within the estuary of the Fraser River. The total area of Sturgeon Bank WMA is 5,152 ha, of which the tidal marsh area is 205 ha. The southern of the WMA is characterized as a brackish marsh, which transitions to a salt marsh as you go north. Human development has influenced this area for almost 200 years. Human activities in this area began in the early 1800s, which included dredging, dyke and entrainment structures, agriculture, and other uses. The areas were designated as WMA in 1998. This area experiences a semidiurnal tidal cycle. The flux tower is located near the southern edge of the marsh, where the dominant species is cattail (Typha latifolia), with a canopy height of 160 cm. The tower is in a high marsh system and was installed to analyze energy, H2O, CO2, and CH4 fluxes on June 1, 2022.
This is the AmeriFlux version of the carbon flux data for the site US-A39 ARM-SGP-Morrison. Site Description - This site is located at ARM SGP Extended Facility 39 near Morrison, OK
This is the AmeriFlux version of the carbon flux data for the site US-UR8 Yellow Jacket - UCRB. Site Description - This site is located in Yellow Jacket, Colorado, on a moderate slope. The area is irrigated using a center pivot system, with alfalfa being the dominant vegetation. The region experiences a temperate climate, characterized by cool to mild temperatures throughout the year and substantial annual precipitation, creating favorable conditions for agricultural activities.
This is the AmeriFlux version of the carbon flux data for the site US-DUF Denver Urban Field Station. Site Description - This site was established on a 25m freestanding former radio tower at the Forest Service's Rocky Mountain Research Station headquarters in Fort Collins, CO. The tower is situated next to a parking lot and several one and two story buildings. To the north and west is the campus of Colorado State University, and to the north and east is low density residential development. To the south and east are a busy intersection and rapid transit bus line, and to the south is green space surrounding the City of Fort Collins' Spring Creek Trail.
This is the AmeriFlux version of the carbon flux data for the site US-MEF Manitou Experimental Forest. Site Description - This site was established on an existing 30-m tower structure at the Forest Service's Manitou Experimental Forest, Colorado. Manitou Experimental Forest is located approximately 38 km northwest of Colorado Springs, within the Pike National Forest. The tower was constructed and used between 2008 and 2013 by NCAR for the BEACHON project and has line power and internet connections. The tower is located in approximately 12 km^2 of ponderosa pine forest and savannah with a land use history of thinning and prescribed burning, though these disturbances have not occurred for many years. The tower is situated in a broad, flat valley that drains to the north. Early research at the site was focused mainly on grazing, while more recently it has turned broadly to the ecology and management of ponderosa pine ecosystems. In 2002, the Hayman Fire burned approximately 56,000 ha to the west and northwest of the tower location.
This is the AmeriFlux version of the carbon flux data for the site US-UR1 Boulder - UCRB. Site Description - This site is located in Boulder, Wyoming, in a high-altitude grassland ecosystem. The region experiences cold winters and mild summers, with relatively low precipitation throughout the year. Snowfall is common during the winter months, contributing to the seasonal water availability. The landscape is primarily covered by grass vegetation, with some areas supported by a center pivot irrigation system, which helps sustain plant growth in the dry environment.
This is the AmeriFlux version of the carbon flux data for the site US-UR2 Cora - UCRB. Site Description - This site is located in Cora, Wyoming, within a high-altitude grassland pasture. The region experiences cold winters with frequent snow cover and mild summers. The land is primarily used for grazing, influencing the vegetation and ecosystem dynamics.
This is the AmeriFlux version of the carbon flux data for the site US-UR3 Ft. Bridger - UCRB. Site Description - This site is located in Fort Bridger, Wyoming, within a flat grassland pasture. The region experiences cold winters with significant snow cover and mild summers. The land is primarily used for grazing, which influences both the vegetation and ecosystem.
This is the AmeriFlux version of the carbon flux data for the site US-UR5 La Plata - UCRB. Site Description - This site is located in La Plata, New Mexico, in a flat terrain and part of a furrow irrigation field. The region has a semi-arid climate, with warm summers and mild winters. The area is primarily covered by alfalfa, which thrives in the irrigated environment.

This is the AmeriFlux Management Project (AMP) created FLUXNET-1F version of the carbon flux data for the site US-Hsm Hill Slough Marsh. This is the FLUXNET version of the carbon flux data for the site US-Hsm Hill Slough Marsh produced by applying the standard ONEFlux (1F) software. Site Description - The site is currently a diked marsh - upland ecotone located at the northern Suisun Marsh. It will undergo tidal restoration in Fall 2021. Restoration work is done by Ducks Unlimited Inc. and will cover an area of 649 acres. After levee breaches, the site tower will be in a high marsh system. Water level at high tide is estimated to be 0.5-1 m above the soil. Ducks Unlimited, Inc. and the Berkeley Biometeorology lab are working together to evaluate the effects of the proposed tidal marsh restoration project.
