Whroo Flux Data Release 2024_v2

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 (v3.4.17) 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).

The site is classified as box woodland, dominated by two main eucalypt species: Eucalyptus microcarpa (grey box) and Eucalyptus leucoxylon (yellow gum). The site has an elevation of 165 m. Mean annual precipitation measured by the nearby Bureau of Meteorology site is 558 mm. Maximum temperatures range from 12.6 °C (in July) to 29.8 °C (in January), while minimum temperatures range from 3.2 °C (in July) to 14.2 °C (in February). Maximum temperatures vary on a seasonal basis by approximately 17.2 °C and minimum temperatures by 11.0 °C.

The instrument mast is 36 m 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.
