Warra Flux Data Release 2022_v2

<br>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 (v3.4.7) 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><em>Eucalyptus obliqua</em> forests dominate the vegetation below 650&nbsp;m where they exist as fire-maintained communities. On fertile soils these forests attain mature heights in excess of 55&nbsp;m: the tallest <em>E. obliqua</em> reaches a height of 90&nbsp;m. The flux station is installed in a stand of tall, mixed-aged <em>E. obliqua</em> forest (77 and >250 years-old) with a rainforest understorey and a dense man-fern (<em>Dicksonia antarctica</em>) ground-layer, on a small flat of elevation 100&nbsp;m adjacent to the Huon River. The understorey vegetation progresses from wet sclerophyll (dominated by <em>Pomaderris apatala</em> and <em>Acacia dealbata</em>) to rainforest (dominated by <em>Nothofagus cunninghamii</em>, <em>Atherosperma moschatum</em>, <em>Eucryphia lucida</em> and <em>Phyllocladus aspleniifolius</em>) with increasing time intervals between fire events. The site supports prodigous quantities of coarse woody debris as is characteristic of these fire-maintained eucalypt forests on fertile sites in southern Tasmania. The soil at the flux site is derived from Permian mudstone and has a gradational profile with a dark brown organic clayey silt topsoil overlying a yellow brown clay. The climate is classified as temperate with a mild summer and no dry season. Mean annual precipitation is 1700&nbsp;mm with a relatively uniform seasonal distribution. Summer temperatures peak in January (8.4&nbsp;°C to 19.2&nbsp;°C) with winter temperatures reaching their lowest in July (2.6&nbsp;°C to 8.4&nbsp;°C).</br>


<br>The instruments are mounted at the top of an 80&nbsp;m tall guyed steel lattice tower. Supplementary measurements above the canopy include temperature, humidity, windspeed, wind direction, rainfall, incoming and reflected shortwave radiation and net radiation. An open-path gas analyser (EC150) was replaced by a closed-path gas analyser (EC155) at the end of January 2015. Soil moisture content is measured using time domain reflectometry. Soil heat fluxes and temperature are also measured. Micro-meteorology (CO<sub>2</sub>, H<sub>2</sub>O, energy fluxes) and meteorology (temperature, humidity, wind speed and direction, rainfall) were measured from 2013 to late 2016, but the dataset is incomplete due to ongoing problems since changing the open-path IRGA to a closed path system (CPEC200) during 2015. Soil data (moisture, heat flux, temperature) are complete for the time period.</br>

Purpose
The purpose of the Warra flux station is to:<ul style="list-style-type: disc;"> <li>study the ecophysiological processes and rates of carbon accumulation and decomposition in a mixed-aged, tall, wet <em>Eucalyptus obliqua</em> forest that experienced natual wildfires</li> <li>measure the exchanges of carbon dioxide, water vapour and energy between the forest and the atmosphere using micrometeorological techniques</li> <li>link ecophysiological processes and rates of carbon accumulations and decomposition with the biota</li> <li>utilise the measurements in combination with remote sensing data and land surface models to upscale the estimate of net exchanges of carbon and water at regional scale.</li></ul>

<br>Processing levels</br> <br>Under each of the data release directories, the netcdf files are organised by processing levels (L3, L4, L5 and L6):<ul style="list-style-type: disc;"> <li>L3 (Level 3) processing applies a range of quality assurance/quality control measures (QA/QC) to the L1 data. The variable names are mapped to the standard variable names (CF 1.8) as part of this step. The L3 netCDF file is then the starting point for all further processing stages.</li> <li>L4 (Level 4) processing fills gaps in the radiation, meteorological and soil quantities utilising AWS (automated weather station), ACCESS-G (Australian Community Climate and Earth-System Simulator) and ERA5 (the fifth generation ECMWF atmospheric reanalysis of the global climate).</li> <li>L5 (Level 5) processing fills gaps in the flux data employing the artificial neural network SOLO (self-organising linear output map).</li> <li>L6 (Level 6) processing partitions the gap-filled NEE into GPP and ER.</li></ul> Each processing level has two sub-folders ‘default’ and ‘site_pi’:<ul style="list-style-type: disc;"> <li>default: contains files processed using PyFluxPro</li> <li>site_pi: contains files processed by the principal investigators of the site.</li></ul> If the data quality is poor, the data is filled from alternative sources. Filled data can be identified by the Quality Controls flags in the dataset. Quality control checks include: <ul style="list-style-type: disc;"> <li>range checks for plausible limits</li> <li>spike detection</li> <li>dependency on other variables</li> <li>manual rejection of date ranges</li></ul> Specific checks applied to the sonic and IRGA data include rejection of points based on the sonic and IRGA diagnostic values and on either automatic gain control (AGC) or CO<sub>2</sub> and H<sub>2</sub>O signal strength, depending upon the configuration of the IRGA.</br> <br>Warra Flux Tower was established in 2013, and stopped measuring in 2021.

Resource lineage

Statement
All flux raw data is subject to the quality control process OzFlux QA/QC to generate data from L1 to L6. Levels 3 to 6 are available for re-use. Datasets contain Quality Controls flags which will indicate when data quality is poor and has been filled from alternative sources. For more details, refer to Isaac et al. (2017).
