This dataset consists of measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer in a pastoral area using eddy covariance techniques.<br /><br /> The flux station is located within an area of dryland agriculture. The surrounding area is dominated by broadacre farming practices. The vegetation cover is predominantly pasture. Elevation of the site is close to 330 m. Climate information comes from the nearby Pingelly BoM AWS station 010626 (1991 to 2016) and shows mean annual precipitation is approximately 445 mm with highest rainfall in June and July of 81 mm each month. Maximumum and minuimum annual rainfall is 775 and 217 mm, respectively. Maximum temperatures range from 31.9°C (in Jan) to 15.4°C (in July), while minimum temperatures range from 5.5°C (in July) to 16.0 °C (in Feb).<br /><br />This data is also available at http://data.ozflux.org.au .

This data release consists of flux tower measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer in semi-arid eucalypt woodland using eddy covariance techniques.

PyFluxPro takes data recorded at the flux tower and process this data to a final, gap-filled product with Net Ecosystem Exchange (NEE) partitioned into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER). For more information about the processing levels, see <a href="https://github.com/OzFlux/PyFluxPro/wiki">https://github.com/OzFlux/PyFluxPro/wiki</a>. <br /> <br /> The site is classified as an open woodland savanna. The overstory is co-dominated by tree species <em>Eucalyptus miniata</em> and <em>Eucalyptus tentrodonata</em>, and average tree height is 14–16m. Elevation of the site is close to 64m and mean annual precipitation is 1750mm. Maximum temperatures range from 30.4°C (in July) to 33.2°C (in November), while minimum temperatures range from 19.3°C (in July) to 25.4°C (in November). Therefore, the maximum and minimum range varies from 7°C (wet season) to 11°C (dry season). <br /><br /> The instrument mast is 23m tall. Heat, water vapour and carbon dioxide measurements are taken using the open-path eddy flux technique. Temperature, humidity, wind speed, wind direction, rainfall, incoming and reflected shortwave radiation and net radiation are measured above the canopy. Soil heat fluxes are measured and soil moisture content is gathered using time domain reflectometry.<br /><br />

Data were processed using PyFluxPro (v3.4.17) 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).</br> <br>The forest is classed as a tall, wet sclerophyll forest, and the dominant <em>Eucalyptus Regnans</em> or mountain ash trees have an average canopy height of 75&nbsp;m. The site contains a chronosequence of (20, 80 and 300) stand ages that were established during fires occurring over the last 300 years. The area is assigned the IUCN Category II (National Parks) of the United Nations’ list of National Parks and protected areas, which means the park is primarily managed for ecosystem conservation. The catchment area is dominated by mountain ash, the world’s tallest flowering plant (angiosperm). Trees can reach heights of more than 90&nbsp;m in areas with high rainfall and fertile soil. Mountain ash forests are confined to the cool mountain regions with elevations ranging from 460 to 1100&nbsp;m and average rainfalls of 1100 to 2000&nbsp;mm/y. These trees are well distributed throughout Victoria’s Central Highlands including the Otway Ranges and Strzlecki Ranges; they are also found in Tasmania. The catchment area contains a portion of the Mt. Disappointment range, the Divide and the headwaters of Wallaby Creek and Silver Creek, and much of the slopes are characterised as flat to moderate.</br> <br>The station itself is located within an old growth stand with individual trees as old as 300 years. Below the dominant canopy lies a temperate rainforest understorey consisting of <em>Pomaderris aspera</em> and <em>Olearia argophylla</em> species, which are 10 to 18&nbsp;m tall. The lower layers of vegetation are dominated by tree ferns (<em>Cyathea australis</em> and <em>Dicksonia antartica</em>) and extensive tracts of rosette and rhizonic ferns (<em>Polystichum proliferum</em> and <em>Blechnum wattsii</em>) as well as acacia trees. The elevation is approximately 720&nbsp;m. The major soil type within the forest is krasnozemic soils, which are friable red/brown soils, with high amounts of organic matter in the upper 20 to 30&nbsp;cm. However, the composition of krasnozemic soils is not homogenous, but rather varies with altitude. Grey-yellow podsolised soils can be found at lower altitudes, while krasnozemic loams is characteristic of the higher altitudes of the Kinglake and of the Hume Plateau. The clay content of these soils increases with depth until at least 200&nbsp;cm deep, where after a transition soils contain rock fragments. The climate of the study area is classified as a cool, temperate zone, with the highest temperatures occurring during the summer months of December – February (13.8 to 22.5&nbsp;°C), whilst the coolest temperatures are experienced in May and August (4.7 to 9.2&nbsp;°C). Average annual precipitation is 1209&nbsp;mm, with a maximum rainfall occurring in June (Ashton, 2000). The study site experiences foggy conditions after sunset during autumn and winter.</br> <br>The original station had a main mast at 110&nbsp;m. This station was destroyed in February 2009 by bushfires. A replacement station was established in March 2010 and started recording in May 2010. The mast sat at a height of 5&nbsp;m. The post-fire instrumentation was not as diverse as the pre-fire instrumentation.</br>
