3.2 Energy balance and carbon flux monitoring
Fluxes and the energy balance are monitored in the near pristine Catchment VI with a full open path eddy covariance (EC) system (OPEC, Campbell Scientific Inc., Logan, Utah, USA), and alongside this soil respiration is monitored with a Li-Cor8100 equipped with eight chambers. Complimented by monthly soil respiration measurements across Catchment III and IX using cost effective techniques. A Large Aperture Scintillometer was installed for a short period in Catchment VI as well. The energy balance components are monitored in Catchments III and IX for use in the Surface Renewal method to solve for total evaporation.
