What they say

Dr. James G. Ogg (Purdue University, USA):

"His Acycle software will become the standard tool for time-scale applications by all international workers."
Dr. J. Fred Read (Virginia Tech, USA):

"It is truly an amazing contribution to the geosciences community. As someone who has spent much of the last 50 years trying to understand cyclic carbonates on shallow platforms, and having been involved with my students in some of the early work on stratigraphic modelling of the effects of Milankovitch forcing of carbonate platform stratigraphy, I was blown away by the power of the Acycle software. ... You should all feel very proud of this contribution. It opens up much needed access to these powerful tools for a wide audience in the sedimentary geology and paleoclimate community. Thanks again for all your efforts. A really marvellous job."

Abstract

Acycle is a comprehensive, but "user-friendly" software package for analysis of time-series designed for (but not limited to) climate research and education.
Acycle runs either in the MATLAB environment or as a stand-alone application on Mac and Windows.
It is an open-source package and is available free of charge.
- Acycle provides data preparation tools, curve fitting, detrending procedures with multiple options available to track or remove secular trends, and integrates various power spectral analysis approaches for detection and tracking of periodic signals.
- Acycle also provides a toolbox that evaluates astronomical signals in climate series and estimates the most likely sedimentation rate by maximizing the correlation coefficient between power spectra of an astronomical solution and a paleoclimate series.
- Many of the functions are specific to paleoclimatology and cyclostratigraphy and are not found in standard, statistical packages.

Mean insolation map from March 21 to Sept. 23 for the past 100 kyr (1-100) at 50-80°N using the Laskar et al. (2004) solutions. The calculate uses a solar constant of 1365 w/m^2.

Evolutionary FFT of the astronomical solution.

2π multi-taper method power spectrum of the gamma ray series is shown with 20% median-smoothed spectrum, background AR(1) model, and 90%, 95%, 99%, and 99.9% confidence levels.
