Yanco 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>This is a topographically flat area, primarily comprised of the following soil types: sandy loams, scattered clays, red brown earths, transitional red brown earth, sands over clay and deep sands. Stream valleys and layered soil and sedimentary materials are found across the landscape.</br>
<br>The flux station tower extends to 20 m, however flux measurements are recorded from slightly lower than this. Mean annual precipitation from the nearby Bureau of Meteorology is 465 mm. Maximum temperatures ranged from 16.6 °C (in July) to 37.4 °C (in January), while minimum temperatures ranged from 11.8 °C (in July) to 29.0 °C (in January). Maximum temperatures varied on a seasonal basis by approximately 20.8 °C and minimum temperatures by 17.2 °C.</br>
<br>The site is within a wider research area (60 x 60 km) that supports a network of flux stations, which have been in operation since late 2001.</br>

- Purpose
- The purpose of Yanco flux tower is to:<ul style="list-style-type: disc;"> <li>provide additional validation data for GCOM-W1 soil moisture products, which are components of a land surface data assimilation system; these data systems are important for land surface models, which rely on atmosphere-surface observations</li> <li>validate the Advanced Microwave Scanning Radiometer-2 (AMSR2) soil moisture product and resulting soil moisture and flux estimates</li> <li>to model crops, runoff, and flood forecasting (Land Surface Model forcing data, i.e. input of AMSR2 soil moisture into the Joint UK Land Environment Simulator - JULES - model).</li></ul>

- <br></br> The site was established in April 2012 as part of a project run with the Japanese Aerospace Exploration Agency (JAXA), and is managed by The University of Western Australia. Primary investigators and contributors are named in the citation. <br />The flux station is part of the Australian OzFlux Network and contributes to the international FLUXNET Network.

- <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>
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).
