Biomet Data (6 Meteo Variables)

For the calculation of Level-1 fluxes in EddyPro, we include 6 meteo variables for improved flux calculation and correction.

The 6 meteo parameters are:

• Global radiation (SW_IN; Rg in EddyPro)
  supported units: W m^-2, J s^-1 m^-2
  Can be used in the “multiple regression” version of the off-season uptake correction (Burba et al., 2008).
• Long-wave incoming radiation (LW_IN, Lwin in EddyPro)
  supported units: W m^-2, J s^-1 m^-2
  Can be used in the “multiple regression” version of the off-season uptake correction (Burba et al., 2008).
• Photosynthetic photon flux density (PPFD or PAR; PPFD in EddyPro)
  units: μmol m^-2 s^-1, μE m^-2 s^-1
  Can be used to assess day and night-time radiation loading on the surface of the instrument, to apply the appropriate coefficients and modeling of the instrument surface temperature in the off-season
  uptake correction.
• Relative humidity (RH)
  supported units: %
  Replaces the mean values as estimated from eddy covariance data or from site characteristics.
• Air temperature (TA; Ta in EddyPro)
  units: K, C, cC, F, cF, cK
  Replaces the mean values as estimated from eddy covariance data or from site characteristics.
  Used e.g. in WPL correction for IRGA75.
• Atmospheric pressure (PA; Pa in EddyPro)
  supported units: Pa, hPa, kPa, PSI, Torr, mmHg, Atm, Bar
  Replaces the mean values as estimated from eddy covariance data or from site characteristics.
