Other Software Tools

In addition to the software available from the Paleoclimatology Program, the following annotated bibliography of software may be useful.

2SAMPLES estimates differences in location (mean, median) and scale (standard deviation, MAD) between two climate data samples and gives bootstrap confidence intervals. Contact Manfred Mudelsee of Climate Risk Analysis for more information on the software. External link to software for two sample data

ANALOG. A program to search for, sort, and select analogs from a reference sample set for a single fossil sample. Several dissimilarity measures can be selected, and modern environmental data can be associated with the reference samples. Published as a USGS open-file report, and distributed by Peter Schweitzer, Mail Stop 955, U. S. Geological Survey, Reston, VA, USA 22092.

BugsMCR. BugsMCR is a piece of free software for producing temperature reconstructions from (fossil) beetle (Coleoptera) data. It allows the creation and/or import of species/sample lists in MS Excel format, and provides both numerical and graphical output as MS Excel files. Graphical output is in the form of TMax(low-high) and TMin(low-high) bar graphs, with the option of exporting thermal overlap matrices (climate space maps) and species lists for each sample.

CABFAC. A program to provide rotated or non-rotated Q-mode factor analysis using a cosine-theta matrix. This program has been used to provide quantitative estimates of past environment from fossil samples by CLIMAP and other groups. CABFAC factors were used with REGRESS to provide an equation relating faunal factors to environment using a linear or non-linear multiple regression. Regress is not generally distributed because this procedure is commonly available in statistical software packages. THREAD was used by CLIMAP and others to hindcast environment from fossil samples using the regression determined by REGRESS. THREAD is not generally distributed because this transformation is also easily accomplished in statistics or spreadsheet packages.

CALPAL. The Cologne Radiocarbon Calibration and Palaeoclimate Research Package. CalPal is a PC-Win program package designed to support research on hominid behavioural response to pleistocene climate change. CalPal allows calendric age-conversion ("calibration") of 14 C-data by a variety of methods (2D-Dispersion, Wiggle Matching, Monte Carlo). The package allows the dating results to be presented in high-quality Postscript graphs in context with climate data (e.g. ice-cores).

CLIM-X-DETECT robustly detects extremes against a time-dependent background in climate and weather time series. Contact Manfred Mudelsee of Climate Risk Analysis for more information on the software. External link to climate extremes detection method

CoralXDS. Coral X-radiograph Densitometry System. CoralXDS is a Windows-based program which provides a tool for measurement of linear extension, density, and calcification from coral X-radiographs. These quantities are determined for high-density, low-density, and annual bands.

DendroClim2002. A statistical tool for analysis of Evolutionary and Moving Intervals in Dendroclimatology. Implementation of bootstrapped correlation and response functions to identify climatic signals in tree rings.

EdGCM. Educational Global Climate Modeling. The EdGCM Project develops and distributes a research-quality global climate model (GCM) with a user-friendly interface that runs on desktop computers.

PaleoSoftTools is a suite of software tools for paleoclimate reconstruction produced at the University of Salamanca

PearsonT calculates Pearson's correlation coefficient between two climate time series. This program gives bootstrap confidence intervals that are valid also in the presence of autocorrelation. Contact Manfred Mudelsee of Climate Risk Analysis for more information on the software. External link to correlation estimation program

RAMPFIT quantifies a climate transition using a nonlinear regression and a search for a global optimum. The bootstrap error bars for the transition parameters take autocorrelation into account. Contact Manfred Mudelsee of Climate Risk Analysis for more information on the software. External link to climate change quantification tool

Singular Spectrum Analysis Toolkit from UCLA Also includes tools for maximum entropy and multi-taper analyses. Described in Dettinger, M. D., et al., Software expedites singular spectrum analysis of noisy time series, EOS, Jan. 10, 1995, pp. 12-21.

TAUEST fits an AR(1) model to unevenly spaced climate time series with bootstrap confidence interval. Contact Manfred Mudelsee of Climate Risk Analysis for more information on the software. External link to autocorrelation analysis software

Wavelet analysis A tool to perform wavelet analysis on time series, including significance and confidence testing, and options to select wavelet types and other parameters. Includes code for IDL, Matlab and Fortran, and has a web form to paste data and obtain results. By Christopher Torrence and Gilbert Compo.
