Mid-latitude ozone monitoring with the GOMOS-ENVISAT experiment version 5: the noise issue
Mid-latitude ozone the GOMOS-ENVISAT experiment version the noise issue

The GOMOS ozone profiles have been analysed to evaluate the GOMOS ability to capture the long-term ozone evolution at mid-latitudes during the expected recovery phase of the ozone layer. Version 5 of ...
Detecting nonlinearity in time series driven by non-Gaussian noise:the case of river flows
nonlinearity time series non-Gaussian noise case of river flows

Several methods exist for the detection of nonlinearity in univariate time series. In the present work we consider riverflow time series to infer the dynamical characteristics of the rainfall-runoff t...

We investigated the influence of atmospheric noise on the generation of interannual El Niño variability. Therefore, we perturbed a conceptual ENSO delay model with surrogate windstress data gen...
Gap filling and noise reduction of unevenly sampled data by means of the Lomb-Scargle periodogram
Gap filling noise reduction Lomb-Scargle periodogram

2009/7/1
The Lomb-Scargle periodogram is widely used for the estimation of the power spectral density of unevenly sampled data. A small extension of the algorithm of the Lomb-Scargle periodogram permits the es...
The DO-climate events are probably noise induced: statistical investigation of the claimed 1470 years cycle
DO-climate event statistical investigation 1470 years cycle
font style='font-size:12px;'>
2008/11/4
The significance of the apparent 1470 years cycle in the recurrence of the Dansgaard-Oeschger (DO) events, observed in the Greenland ice cores, is debated. Here we present statistical significance tes...
