Fig. 9

a Time series of the standardized daily average for the residuals of soil CO2 flux. Only values > 2σ are colored with red. A1–A5 denote the CO2 flux anomalies discussed in the text. The main volcanic and seismic events are shown in the top of the figure. b Time series of the daily average of the environmental parameters that were included in the model. From the top, barometric pressure (black), wind speed (blue), air temperature (green), soil temperature (orange), and soil humidity (purple) are shown
