Calibration Information
 Infrared gas analyzer of EC system was calibrated approximately in every
 6 months with standard CO2 gases and a dew point generator (LI610,
 Li-Cor).
 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 2 year.
