Cleaned CO2 Net Ecosystem Exchange

Cleaned flux values from the eddy covariance towers

The standard data use policy applies to the this dataset

Context:

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.

Experiment: Scale-up Biofuels Experiment - GLBRC
Temporal Coverage: 2009-01-01 to 2009-12-31
