On the Optimization of Singular Spectrum Analyses: A Pragmatic Approach
Fernando Lopes, Dominique Gibert, Vincent Courtillot +2
Singular Spectrum Analysis (SSA) occupies a prominent place in the real signal analysis toolkit alongside Fourier and Wavelet analysis. In addition to the two aforementioned analys…
On the mechanism of thermal self-regulation of trees: a kind of homeothermic observation
Jean-Baptiste Boulé, Jean de Bremond d'Ars, Vincent Courtillot +6
What is certain is that surface temperatures around the globe vary considerably, regardless of the time scales or underlying causes. Since 1850, we have observed an average increas…
Information theory, Signal Analysis and Inverse Problem
Dominique Gibert, Fernando Lopes, Vincent Courtillot +2
This book is intended for teaching Signal Analysis methods and Inverse Problems theory. It is completely open access and will remain free. It is currently illustrated with examples…
On the effect of the luni-solar gravitational attraction on trees
Jean-Louis Le Mouël, Dominique Gibert, Jean-Baptiste Boulé +5
In this paper, we revisit old electrical measurements conducted on a poplar tree in 2003 (Gibert et al. 2006), which showed the presence of a diurnal electrical signal, attributed…
On the tilt of the Earth's polar axis (climat): Some 'impressionist' remarks
V. Courtillot, F. Lopes, V. Kossobokov +4
In this lengthy letter, we wanted to discuss the concept of climate based on definitions established for over a century and direct observations that we have been collecting for mor…
A living forest of Tibetan Juniper trees as a new kind of astronomical and geophysical observatory
Vincent Courtillot, Jean-Baptiste Boulé, Jean-Louis Le Mouël +5
The trajectory of Earth about the Sun is perturbed by torques exerted by the Moon and Sun, and also the four giant planets. These provoke variations of insolation at Earth surface,…
On the external forcing of global eruptive activity in the past 300 years
J-L. Le Mouël, D. Gibert, V. Courtillot +11
The decryption of the temporal sequence of volcanic eruptions is a key step in better anticipating future events. Volcanic activity is the result of a complex interaction between i…
On distributions law of planetary rotations and revolutions as a function of aphelia, following Lagrange's formulation
F. Lopes, V. Courtillot, D. Gibert +2
Earth rotation is determined by polar motion (PM) and length of day (lod). The excitation sources of PM are torques linked to fluid circulations ("geophysical excitations"), and th…
