increase of CO2 in the atmosphere is the impact of the anticipated climate change on the ve...
The origin and detection of spike-like anomalies in soil gas radon time series
radon detection spike-like anomaly
2017/4/12
Desorption of radon is of short duration but longer than telluric noises and is usually accomplished in less than one
minute based on our binary event counting with a 16 second interval. Adapting an ...

Nonlinear time series analysis geomagnetic pulsations
2009/11/16
A detailed nonlinear time series analysis has been made of two daytime geomagnetic pulsation events being recorded at L'Aquila (Italy, L ≈ 1.6) and Niemegk (Germany, L ≈ 2.3). Grassberger and Procacci...
Using modern time series analysis techniques to predict ENSO events from the SOI time series
modern time series analysis techniques ENSO events SOI time series
2009/11/12
We analyze the monthly 1866-2000 Southern Oscillation Index (SOI) data to determine:
1) whether the SOI data are sufficiently noise-free that useful predictions can be made from them, and 2) in part...
Cross recurrence plot based synchronization of time series
