Eddy Correlation System

Eddy Correlation System

A flux tower records latent and sensible heat flux using a CSAT 3D sonic anemometer and a Licor 7500 gas analyser, both mounted on a tripod three metres above the ground. Data are measured at 10Hz and 30 minute averages are recorded.

Other data recorded at the site includes:
* Incoming & outgoing long and short wave radiation (CNR1 Kripp & Zonen instrument mounted 1 metre above ground - 30 minute averages)
* Soil heat flux (two HFT3 plates and TCAV thermocouple temperature probes 8cm below the surface - 30 minute averages)
* Air temperature and relative humidity (HMP45C probe mounted two metres above ground - 30 min average).
