Trace Gas Fluxes

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.
