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

Figure 4

Contribution of the different frequency components (annual, intermediate, and daily) to the global gas ²²²Rn (a) and CO₂ (b) concentrations. The subfigures are not coincident in the time domain because they represent the maximum available continuous measurement range with the absence of missing data.
