TERN SuperSites are Long Term Ecological Research (LTER) sites co-located with TERN OzFlux eddy covariance towers, which deliver biological and environmental observations of flora, fauna, microbial biodiversity, soils and hydrology. TERN OzFlux delivers micrometeorological observations of energy, carbon and water exchange between the atmosphere and key Australian ecosystems. Each TERN SuperSite is located in a significant Australian biome and the network spans a wide range of environmental conditions.
