CO2 Net Ecosystem Exchange via Flux Tower — GLBRC Scale-up Experiment

Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Cleaned flux values from the eddy covariance towers at the GLBRC Biofuel Scale-up sites. Tower 1 – “CRP Switchgrass”, Tower 2 – “CRP Prairie”, Tower 3 – “CRP Corn”, Tower 4 – “AGR Corn”, Tower 5 – “AGR Switchgrass”, Tower 6 – “AGR Prairie”, Tower 7 – “Reference”.

This datatable is part of the KBS GLBRC CO2 Net Ecosystem Exchange using Eddy Covariance method dataset. 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.
