Cleaned CO2 Net Ecosystem Exchange
Cleaned flux values from the eddy covariance towers
The standard data use policy applies to the this datasetContext:
The eddy covariance tower method is used to make continuous measurements of the carbon dioxide net ecosystem exchange (NEE). There are 7 towers on KBS GLBRC scale-up fields; 3 at Lux Arbor Reserve and 4 at the the Marshall Farms fields.
