Three gases were measured: carbon dioxide, methane and water vapor.  Simultaneous measurements of environmental drivers are also measured and recorded as half-hourly values: photosynthetic photon flux density, downwelling and upwelling short and long wave radiation, air temperature, relative humidity and precipitation.  Variable names and units follow AmeriFlux and FLUXNET standards.
