Insights on Climate-Driven Fluctuations of Cave ²²²Rn and CO₂ Concentrations Using Statistical and Wavelet Analyses

Figure 6

Observed and predicted values of CO₂ increments considered for the different cave stages: (a) stage 1 (gaseous recharge), (b) stage 2 (maximum gas concentration in the cave), (c) stage 3 (gaseous discharge), and (d) stage 4 (minimum gas concentration in the cave). Predicted values are obtained in each case considering the predictor variables established in the PCA (Table 1). The unstandardized coefficient (coefficient) of each predictor variable within the multivariate analysis as well as its weight (standardized coefficient) is shown for each individual prediction. indicates significant variables in the multivariate analysis.
