  • This dataset contains time series of turbulent exchange of CO2, heat, momentum, O3 and particles measured at two heights at SMEAR II research station near Hyytiälä Forestry Field Station, Juupajoki, Finland, during years 1997–2018. The flux measurements were done with several measurement setups above the forest and at 3 m height below the canopy.

  • The Bartlett Experimental Forest is relocateable site in Domain 01 Northeast and the site is part of NEON's sampling design. The site is located in New Hampshire. BART extends from the village of Bartlett in the Saco River valley at 680 ft to about 3,000 ft at its upper reaches. Aspects across the forest are primarily north and east. This particular site was chosen because it represented conditions (soils, elevation, climate, tree species composition) typical of many forested areas throughout New England and northern New York. An actively managed forest: manged protions (30% reflect a range of forest patch sizes and structural distrubutions. Sampling area is 15.66 km^2. . Airborne remote sensing surveys of this field site collect collect lidar, spectrometer and high-resolution RGB camera data. The flux/meterological tower at this site is 116’ with 6 measurement levels. The tower top extends above the vegetation canopy to allow sensors mounted at the top and along the tower to capture the full profile of atmospheric conditions from the top of the vegetation canopy to the ground. The tower collects physical and chemical properties of atmosphere-related processes, such as humidity, wind, and net ecosystem gas exchange. Precipitation data are collected by a tipping bucket at the top of the tower and a series of throughfalls located in the soil array. This site has five soil plots placed in an array within the airshed of the flux tower. Field ecologists collect the following types of observational data at this site: Terrestrial organisms (birds, ground beetles, mosquitoes, plants, small mammals, soil microbes, ticks), Biogeochemical data, and and soil data. Total data products collected at this site is 116.

  • Gingin Banksia Woodland SuperSite is located on the Swan Coastal Plain, approximately 10 km southwest of Gingin, near Perth, Western Australia, sited on land traditionally owned by the Yued group of the Noongar people. The site has an elevation of 51 m and 2 km from the University of Western Australia International Gravity Wave Observatory. The Gingin Banksia Woodland SuperSite is located in a natural woodland of high species diversity (overstorey dominated by Banksia spp.) that overlays the Gnangara groundwater mound, Perth’s most important groundwater resource. The mean annual precipitation is 641mm for this coastal heath woodland. The overstorey is dominated by Banksia spp. mainly B. menziesii, B. attenuata, and B. grandis with a height of around 7 m and leaf area index of about 0.8. There are occasional stands of eucalypts and acacia that reach to 10 m and have a denser foliage cover. There are many former wetlands dotted around the woodland, most of which were inundated all winter and some had permanent water 30 years ago. The water table has now fallen below the base of these systems and they are disconnected and are no longer permanently wet. The fine sediments, sometimes diatomaceous, hold water and they have perched water tables each winter. There is a natural progression of species accompanying this process as they gradually become more dominated by more xeric species. The soils are mainly Podosol sands, with low moisture holding capacity. Field capacity typically about 8 to 10%, and in summer these generally hold less than 2% moisture. The water table is at about 8.5 m below the surface, and a WA Dept of water long-term monitoring piezometer is near the base of the OzFlux tower. The Swan Coastal Plain bioregion consists of five main geomorphic entities that are roughly located parallel to the coastline including three coastal sand dune systems with ages increasing inland from the coast. Banksia Woodlands is restricted to the Swan Coastal Plain IBRA bioregion and immediately adjacent areas, including the Dandaragan plateau. Vegetation consists of a prominent tree layer of Banksia with scattered eucalypts and other tree species present within or emerging above the Banksia canopy, and a diverse understorey including sclerophyllous shrubs, graminoids and forbs. The Gingin SuperSite is collocated with the Land Ecosystem Atmosphere Program (LEAP) - Gingin. The traditional owners at Gingin are the Yued group of the Noongar People.

  • McDiffett Creek (MCDI) is located within the Urban Prairie Research Area approximately 25 km southeast of the KONZ tower. [2] It is a second-order perennial stream flowing through the middle of agricultural land. The Urban Prairie Research Area is a small tract of land composed of native prairie, grazing, hay, and historically cultivated fields. It is managed by the Konza Prairie Biological Station in association with Kansas State University and is located in the Flint Hills region of Kansas just 10km south of Manhattan, KS. The MCDI site is encompassed in the NEON Prairie Peninsula Domain, which includes the largest remaining areas of unplowed tallgrass prairie in North America. The Prairie Peninsula domain consists of grasslands, forests, and agricultural cover types. The Domain hosts four other NEON field sites, one other aquatic and three terrestrial, all of which are located in Kansas. Remote sensing surveys of this site collect lidar, spectrometer and high resolution RGB camera data. This site has one meteorological station located in the riparian area.

  • The Boyagin Wandoo Woodland SuperSite was established in September 2017 by the University of Western Australia. Located in the Boyagin Nature Reserve, approximately 12 km west of Pingelly, Western Australia the SuperSite monitoring activities complement the Avon River Catchment Critical Zone Observatory at the UWA Future Farm in Pingelly that focusses on managed landscapes (rotational dryland wheat cropping and grazing pastures for sheep). The climate is Semi-arid (Dry) Warm Mediterranean. The Boyagin SuperSite is collocated with the Land Ecosystem Atmosphere Program (LEAP) - Boyagin. Boyagin SuperSite is located in the Avon Wheatbelt (AW2-Re-juvenated Drainage subregion) and has a high density of rare and geographically restricted flora and supports populations of several marsupials subject to fox predation (Numbat, Quenda, Woylie, Tammar, Red-tailed Phascogale, Brushtail Possum) that have disappeared from most of the Australian or Western Australian mainland. The Noongar people are the traditional owners at Boyagin.
