Howard Springs Flux Data Release 2022_v2
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. It been processed using PyFluxPro (v3.4.7) as described in Isaac et al. (2017), <a href=" https://doi.org/10.5194/bg-14-2903-2017">https://doi.org/10.5194/bg-14-2903-2017</a>. 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 />

- Purpose
- The primary purpose of the Howard Springs Flux Station is to understand the effects of fire on heat, moisture and carbon dioxide fluxes in Australia's tropical savannas. Other aims include: <br /> to examine the water and carbon exchanges of tropical savannas <br /> understand the process of carbon cycling and storage in tropical savannas <br /> provide longer term measurements for future projects.

- Credit
- The site is managed by the University of Western Australia and Charles Darwin University and supported by TERN. The flux station is part of the Australian OzFlux Network and contributes to the international FLUXNET Network.

Data quality info
- Hierarchy level
- Dataset
- Other
- 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 (i) range checks for plausible limits, (ii) spike detection, (iii) dependency on other variables and (iv) manual rejection of date ranges. 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 CO2 and H2O signal strength, depending upon the configuration of the IRGA. For more details, refer to Isaac et al (2017) in the Publications section, https://doi.org/10.5194/bg-14-2903-2017. For further information about the software (PyFluxPro) used to process and quality control the flux data, see https://github.com/OzFlux/PyFluxPro/wiki .
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) in the Publications section, https://doi.org/10.5194/bg-14-2903-2017 .
