Gwangneung Deciduous forest
 
Calibration Information
Open-path analyzers were calibrated approximately in every 6 months with standard CO2 gases and a dew point generator(LI610, Li-Cor, USA)
The CO2/H2O concentration profile system is being calibrated once a day for the zero (CO2, H2O) and span CO2 concentration. H2O span is being manually calibrated once a week.
Other micrometeorological instruments are being calibrated approx. once in every 6 months.
