Measurements
At Scott Farm, fluxes of heat, water vapour and carbon dioxide are measured using the open-path eddy flux technique. Supplementary measurements include air temperature and humidity, wind speed, wind direction, rainfall, PAR and net radiation. Soil moisture content, soil heat fluxes and temperature are also measured.
To allow calculation of the carbon budget of the grazed pasture in the footprint, non-CO2 carbon fluxes (e.g. imported feed, exported silage, exported milk, methane) are also measured or estimated.
