Most Important Variables

Lists will be complemented as needed.

The following gives a list of variables that are widely used in ecosystem research and should be included in shared datasets (if available).

Flux Variables

NEE (µmol CO₂ m^-2 s^-1): Net ecosystem exchange of CO₂
GPP (µmol CO₂ m^-2 s^-1): Gross primary production
RECO (µmol CO₂ m^-2 s^-1): Ecosystem respiration
LE (W m^-2): Latent heat flux
H (W m^-2): Sensible heat flux
Quality flags for NEE, GPP, RECO, LE and H, to differentiate between directly measured and gap-filled fluxes

TA (°C): Air temperature
SW_IN (W m-2): Incoming shortwave radiation
LW_IN (W m-2): Incoming (down-welling) longwave radiation
PPFD (umol m-2 s-1): Incoming photosynthetic photon flux density
RH (%): Relative humidity
PA (kPa): Atmospheric pressure
PREC (mm): Precipitation total
SWC (%): Soil water content (volumetric)
TS (°C): Soil temperature
G (W m-2): Ground heat flux, needed for the energy balance closure calculations
NETRAD (W m-2): Net radiation, needed for the energy balance closure calculations
VPD (hPa): Vapor pressure deficit
