Atmospheric CO₂ Daily Volatility Time Series

This dataset contains daily atmospheric CO₂ measurements and their calculated volatility. The volatility series captures the short-term variation of CO₂ concentration, computed as rolling standard deviations over a 30-day window. Additionally, a residual-based volatility is included, representing fluctuations after removing long-term trends. This dataset is intended for research on time-series dynamics, anomaly detection, and studying pre-indicator patterns in atmospheric CO₂ levels.
