BlackOut: whether the clear chamber was covered or not. Tair_Avg: average temperature in the chamber during the gas flux measurement, in degree centigrades. RH_Avg: average relative humidity in the chamber during gas flux measurement, in percent. PAR_umol_Avg: average photosynthetically active radiation during gas flux measurement, in micromol per square meter per second. flux_co2: CO2 flux in micromol CO2 per square meter per second. flux_ch4: CH4 flux in nanomol CH4 per square meter per second. sampling date: date and time of the gas flux measurement. instrument: analyser used to detect CO2 and/or CH4, either a Los Gatos Research Ultra-Portable GHG analyser (LGR) or a Vaisala GMP343 Carbon Dioxide Probe (Vaisala). moisture_soil: moisture content of the soil at the time of sampling, in percent of oven-dry weight.
