description: Supplementary Material 1. Fig. S1: Trial set-up for the two aerobic emission measurement periods, here for the first aerobic measurement period (starting at ensiling day 30). Table S1: Allocation of actual measurement time points to the measurement analysis intervals for ANOVA analyses of gas emission quantities during the aerobic measurement periods. Table S2: Chemical composition and energy concentration of fresh maize and ensiled material for the silage treatments in Experiment A2 (unless otherwise stated). Table S3: Chemical composition, the V-Score and microbial counts of fresh maize and ensiled material for the silage treatments in Experiment A2. Table S4: Silo face characteristics for the barrel silos in Experiment A1 and silage treatments at silo opening at ensiling day 30 (right before the first aerobic emission measurement period started). Table S5: Silo face characteristics for the barrel silos in Experiment A1 and silage treatments at silo opening at ensiling day 135 (right before the second aerobic emission measurement period started). Table S6: Classification and range of different phases of aerobically stored silage material, and duration of phases and silage temperatures for the different silage treatments examined. Table S7: Regression and rS for the correlations between carbon dioxide (CO2) emission mass flow [(mg CO2) kgDM–1] and the time after silo opening (phase A) and the temperature difference between the silage material and the ambient air temperature (phases B–D) during the aerobic emission measurement periods. Fig. S2: Correlation between CO2 concentrations measured within the exhaust air during the first aerobic emission measurement period (barrel opening on ensiling day 30) using the GC or PAS measurement methodology and technology (Sects. "Set-up and procedure of the aerobic emission measurement periods" and "Measurement of the silage emission mass flow rate"). Fig. S3: CO2 emission mass flow, ambient air and silage material temperatures of the silage barrels (mean values) containing each silage treatment during the second aerobic emission measurement period (opening on ensiling 135). Fig. S4: CO2 emission mass flow, ambient air and silage material temperatures of the silage barrels (mean values) containing each silage treatment during both aerobic emission measurement periods (AEMP1 and AEMP2). Fig. S5: CO2 emission mass flow during the heating process as a function of the temperature difference between the silage and the ambient air temperature (23.7 ± 0.4 °C) during AEMP1 and AEMP2 (23.7 ± 0.2 °C, respectively). Fig. S6: Ethanol and ethyl acetate emissions and ambient air and silage material temperatures of the silage treatments during the second aerobic emission measurement period (opening on ensiling day 135). Fig. S7: Ethanol and ethyl acetate emission mass flow, ambient air and silage material temperatures of the silage barrels (mean values) containing each silage treatment during both aerobic emission measurement periods (AEMP1 and AEMP2). Table S8: Cumulative CO2, CO2eq, ethanol and ethyl acetate emissions during the first aerobic emission measurement period (silos opened at ensiling day 30). Table S9: Cumulative CO2, CO2eq, ethanol and ethyl acetate emissions during the second aerobic emission measurement period (silos opened at ensiling day 135).
