Metadata for the CO2, CH4 and CO2equivalent flux measurement data modeling associated with measurements in Niron et al. 
Exploring the Synergy of Enhanced Weathering and Bacillus subtilis: A Promising Strategy for Sustainable Agriculture. 

GHGData is the data structure including the following data columns:
Flux (µmolCO2m2s/µmolCH4m2s): CO2 flux data (the change in the sum of 12CO2 and 13CO2 values between the initial and final values) or CO2equivalent flux data (CO2 flux summed with CH4 flux converted to CO2) or CH4 flux data
SWC: soil water content at the time of CO2 concentration measurement
temperature: the temperature at the time of measurement
Mesocosm_no: mesocosm where measurement was done (1-20)
Day: the day of measurement
Basalt_bin: a binary indicative of basalt presence
Bacillus_bin: a binary indicative of B. subtilis presence

Information regarding the data compilation and lmer model:

The µmolCO2m2s/µmolCH4m2s, SWC, and temperature data were mapped on histograms to remove strong outliers. The CO2 flux values smaller than 0.1 and larger than 8 were eliminated to correct for the skewness. SWC values smaller than 0.1 were eliminated to correct for the skewness.

model8 was selected for temperature and SWC normalization as it generated a residual dataset with the best visually and mathematically normal distribution among the models.
