Site Description

The Virginia Park flux station was located on a cattle grazing property near Charters Towers, Queensland (GPS coordinates: -19.8833, 146.5539).

The Eucalyptus trees in this wet-dry tropical savannah ecosystem were 8-10m tall and the height of the instrument mast was 27m. Elevation of the site was 200m and mean annual precipitation was 700mm, falling predominantly in the wet season (November - March) and highly variable in time and space.

Fluxes of heat, water vapour and carbon dioxide were measured using the open-path eddy flux technique. Supplementary measurements above the canopy included temperature, humidity, windspeed, wind direction, rainfall, incoming and reflected shortwave radiation and net radiation. Profiles of temperature, humidity and CO2 were measured at seven levels within the canopy. Soil moisture content was measured using Time Domain Reflectometry, while soil heat fluxes and temperature were also measured.
