  "description": "Wind speed, wind direction (3D) and gas concentrations are measured at 10 Hz and statistically processed using the eddy covariance technique to half-hour estimates of flux rates of gas exchange between the ecosystem and atmosphere.  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.  This site is a flotant herbaceous freshwater marsh in Salvador Wildlife Management Area near Luling, LA.",
