This dataset consists of measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer in Nirranda South using eddy covariance techniques.
The Otway flux station was located at Narrinda South in south west Victoria, Australia.The pasture was grazed by dairy cattle with average grass height of 0.1m. Annual average rainfall at the site was around 800mm and was only moderately seasonal. Mean daily temperature ranged from 25°C in February to 12°C in July. The flux station was situated on a 10m tower. Fluxes of heat, water vapour and carbon dioxide were measured using the open-path eddy covariance technique. Supplementary measurements included temperature, humidity, rainfall, total solar, photosynthetically active radiation (PAR) and net radiation. Soil temperature and heat flux were also measured. The Otway flux station was established in February 2007 on private land at Nirranda South and managed by CSIRO Marine and Atmospheric Research staff as part of the Cooperative Research Centre for Greenhouse Gas Technologies.

The Otway flux station managed by CSIRO Marine and Atmospheric Research staff as part of the Cooperative Research Centre for Greenhouse Gas Technologies.
The Otway flux station is supported by CO2CRC. Equipment was provided by CO2CRC.
The purpose of the Otway flux station was to :
measure exchanges of carbon dioxide, water vapour and energy between the soil and the atmosphere using micrometeorological techniques.
participate in the atmospheric monitoring strategy, which was developed by CO2CRC researchers in CSIRO, and is based on the effects of hypothetical storage leaks (point and diffuse) simulated by atmospheric dispersion models, over several distance scales at the Otway site.
The Otway Project included injection and geological storage of up to 100,000 tonnes of carbon dioxide together with the most extensive monitoring and verification program yet undertaken at a geosequestration site.
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.
