Trace Gas Fluxes — GLBRC Biofuel Cropping System 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Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
N2O, CO2 and CH4 gas flux data from KBS and Arlington Biofuel Cropping System Experiments. Fluxes were measured using static gas flux chambers. Fluxes have been corrected to air temperature on the day the flux was measured.
This datatable is part of the GLBRC Trace gas monitoring dataset. Measurements from static chambers are taken every two weeks during the growing season.

| subplot | microplots. Also, "no_cover" represents small plots with cover crop removed for a 2-year study to investigate the effects of the presence or absence of cover crops on nitrous oxide (N2O) emissions carried out by Neville Millar. | |
| n2o n | gas flux of nitrous oxide as N | g/ha/day |
| ch4 c | gas flux of methane as carbon | g/ha/day |
| co2 c | gas flux of carbon dioxide as carbon | g/ha/day |
| temperature | Air temperature used to correct the gas flux. KBS air temperature is measured at 10 am at 3 meters above the ground. | celsius |
| chamber | the chamber measured. Most of the time only one chamber was measured but sometimes 2 chambers were measured. |
