Litchfield Flux Data Release 2026_v2_subset

<p><br></p><p>This release consists of flux tower measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer using eddy covariance techniques. Data were processed using PyFluxPro (v3.4.24) as described by Isaac et al. (2017). PyFluxPro produces a final, gap-filled product with Net Ecosystem Exchange (NEE) partitioned into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER).</p><p><br></p><p>Located in a 5 km2 block of relatively uniform open-forest savanna, the site is representative of high rainfall, frequently burnt tropical savanna.</p><p><br></p><p>Tropical savanna in Australia occupies 1.9 million km2 across the north and given the extent of this biome, understanding biogeochemical cycles, impacts of fire on sequestration, vegetation and fauna is a national priority. In the NT, savanna ecosystems are largely intact in terms of tree cover, with only modest levels of land use change. Despite this, there is evidence of a loss of biodiversity, most likely due to shifts in fire regimes and a loss of patchiness in the landscape. Approximately 40 % of the savanna burn every year and understanding fire impacts on fauna and flora is essential for effective land management.</p><p><br></p><p>The 2026_v2_subset is a subset of the original data, a number of variables were reduced after resolving some errors encountered in previous versions.</p>
