Free Software


The World Data Center for Paleoclimatology in Boulder distributes several software packages for use on an As-Is basis: we cannot provide any support nor can we guarantee the software's performance. We encourage authors of any software of interest to the paleoclimatic community to contribute their software for distribution on this page. Please contact us for more information.
AnalySeries AnalySeries MacIntosh time series analysis tool by Didier Paillard, LSCE. The latest version of AnalySeries is compatible with Mac OSX and is available at the LSCE website. The software is posted as a stuffit archive (.zip) file. The file can be downloaded, then opened with Stuffit Expander (a free utility available at http://www.stuffit.com/mac/expander/). For further information please contact Didier Paillard (didier.paillard@lsce.ipsl.fr). Previous versions (v.1.*) formerly distributed here by WDC Paleo are not compatible with current Mac operating systems.
ANOVA ANOVA (Analysis Of Variance). Tingley (2012) Bayesian ANOVA Scheme for Calculating Climate Anomalies. Matlab code for two-factor (location and year) analysis-of-variance model for the calculation of climate anomalies, in which the reference interval is specified as the full length of the dataset. This scheme avoids the affects of shorter (e.g. 1961-1990) reference intervals on the temporal evolution of the spatial standard deviation of climate anomalies.
Arand Arand Time series and spectral analysis software package written by Philip Howell at Brown University. The software allows the user to assign time to depth from an age model, interpolate data at an even time step, perform spectral and cross-spectral analysis, and filter data.
Atlantic Abyssal Circulation Atlantic Abyssal Circulation Model Code Marchal and Curry (2008) Fortran code to calculate abyssal circulation in the Atlantic Ocean utilizing hydrographic or paleoceanographic input parameters.
BARCAST BARCAST (Bayesian Algorithm for Reconstructing Climate Anomalies in Space and Time). Tingley and Huybers (2009) Matlab code uses a hierarchical Bayesian model to assimilate both proxy and instrumental data sets, and estimate the probability distribution of all model parameters and the climate field through time on a regular spatial grid.
C2 C2 New! Those interested in software for developing transfer functions or plotting stratigraphic diagrams may want to look at a new Windows program, C2, written by Steve Juggins at Newcastle University. C2 is free to download and use but the data analysis and graphics functions are restricted to a maximum number of 75 samples. A license file that removes this restriction must be purchased to use C2 with larger datasets.
HIBAL Hydrologic Isotopic Balance Program HIBAL Hydrologic Isotopic Balance Model for Paleolake Systems. Benson and Paillet (2002) FORTRAN code for a simple hydrologic-isotopic-balance model for application to paleolake d18O records. Inputs to the model include discharge, on-lake precipitation, evaporation, and the d18O values of these fluid fluxes.
MapPad MapPad (for Microsoft Windows) is a program with which you save your site and associated text information to a simple text file, and then display it by clicking points on a map. Continental and regional maps are provided.
PaleoVu PaleoVu (Version 1.0 for Macintosh and Windows 3.1) is a complete browse and visualization tool for all types of paleoclimate and paleoecological data. Point and click to create queries, list site information, display or plot variables and data, or export the data for further processing and analysis. Note: PaleoVu is no longer maintained or supported. Data content is not being updated, and compatibility problems may exist with newer operating systems. PaleoVu is still suitable as a teaching tool, but our internet-based browsing tools are the most up to date source for paleoclimatic data.
PalyHelp PalyHelp New! A suite of six programs from L.J. Maher, Jr. at the University of Wisconsin. Includes programs for solving Mosimann's equations for confidence limits, and programs for solving and testing pollen concentration data. These programs run on Microsoft Windows, but the (Basic) source code is also available.
RedFit RedFit New! RedFit software estimates red-noise spectra directly from unevenly spaced time series, without requiring interpolation.
Showtime ShowTime (Version 0.6 for Microsoft Windows, data file updated 6 April 1998) is an animation that displays the distribution through space and time of individual pollen taxa. Currently, data are available only for North America for the past 15ka B.P. (Click the icon to download. The size of the self-extracting executable file is approximately 1.7 Mbytes.)
SiteSeer SiteSeer (Version 1.1 for Microsoft Windows) for browsing the contents of a pollen database, displaying summary information and summary pollen diagrams.
Beerling 2009 SI-CO2 Stomatal Index-CO2 Statistics Beerling et al. (2009) MATLAB code for estimating ancient atmospheric CO2 and confidence intervals from leaf Stomatal Index (SI) proxy data.
VSlite VS-Lite Vaganov-Shashkin-Lite Model of Tree-Ring Width. A simple, efficient, process-based forward model of tree-ring growth, requires as inputs only latitude and monthly temperature and precipitation.
See How to... for guidance in retrieving and decompressing these applications.
We have an annotated list of additional software available from other sources. Additions to this list are welcome.
PANGAEA-Network software for visualization, exploration and interpretation of scientific data.
