Open Source MATLAB Earth Sciences Software for Mac

The EPC software calculates velocities for any points located on the earth’s surface given the Euler pole parameters and estimates the Euler pole parameters given the observed velocities of a set of sites located on a tectonic plate. Since version 2, the software is able to estimate or apply the Plate Translation Rates, as well. Please cite one of the following papers when you use the software: - Goudarzi, M A, Cocard, M, and Santerre, R. 2014."EPC: Matlab Software to Estimate Euler Pole Parameters".

DOI: 10.1016/j.geog.2025.03.004. * The element G_23 of the Jacobian matrix of linearized observations in formula 18 (page 4) in this paper has an incorrect sign (minus sign should be removed).

Development of new data assimilation techniques for ocean models

The Matlab SRTM Library is designed to be an easy-to-use interface for importing and manipulating NASA's Shuttle Radar Topography Mission (SRTM) Digital Elevation Model (DEM) dataset.

Folder is a tool to simulate and analyse the development of structures in mechanically layered media during layer parallel shortening or extension. It includes a graphical user interface that allows for easy designing of complex geometrical models, defining material parameters (including linear and non-linear rheology), and specifying type and amount of deformation. It also includes a range of features that facilitate the visualization and examination of various relevant quantities e.g. velocities, stress, rate of deformation, pressure, and finite strain. Folder contains a separate application, which illustrates analytical solutions of growth rate spectra for buckling and necking of a single viscous layer.

GPS Date Converter (GDC) is a program to convert six different date formats, including: (1) Decimal year, (2) Year, Month, Day, (3) Year, Day of year, (4) GPS Week, Day of week, (5) Julian date, and (6) Modified Julian date. These formats are quiet common in Earth Sciences, specially GPS applications. More information can be found in the GDC website.

Along with calculating basic statistics and quality parameters such as mean and variance, the soft-ware is capable of importing and visualizing different standard time series formats, determining and removing jumps and outliers, and makes numerical and publication quality graphical outputs. Bivariate statistical analysis (including correlation coefficient and linear regression) and time series analysis (including auto and cross-spectral analysis, wavelet power spectrum, spectrogram and periodicities) form the main analysis features of the software.

A MatLab toolbox with many simple and useful functions for analyzing data from Cluster, Champ and the Swarm missions. Other functions for space plasma physics, magnetospheric and ionospheric research are included. The toolbox is designed to be as simple as possible. Each function can be learned and used individually. See the tutorial in the Files section for a quick introduction.

Matlab freeware for data analysis, by J. M. Lilly

PSIworxR (R) and PSIworx (MATLAB) are a collection of functions and scripts to analyze data from the PSI SuperHead Fast Fluorometer series (www.psi.cz). These fluorometers are used in limnology and oceanography research communities. The program retrieves parameters from single turnover induction and relaxation. Results are returned as text files and PDF figures.

Software for automated acquisition and analysis of paleomagnetic and rock magnetic data using the RAPID System.

Provides an API, which enables the Matlab or Octave user (and developer) to incorporate Space Weather data and metadata resources from the Space Physics Interactive Data Resource (SPIDR) directly into an Matlab/Octave application. Examples included.

The SeismoWeb Toolbox is a collection of Matlab and Java tools providing access to seismological webservices. The current focus lies on the NERIES earthquake data portal, but it is intended to add more webservices in the future.

Star Identification from star position measurements, for use with telescopes, cameras, and star trackers.

TP-Fit is used to analyze downhole temperature measurements by extrapolation of transient data to undisturbed formation temperatures. This is an OLD version, the latest versions TP-Fit can be found at https://github.com/MHee/TP-Fit !!!

The purpose of the software is to calculate the undulation between the WGS84 ellipsoid (GPS height) and the EGM96 geoid (mean sea level) in MATLAB, based on the C code in the "egm96-f477.c" project

With the support of the NSF and ONR over the past few years we have developed a MATLAB tool that calculates the internal wave field generated by barotropic tidal flow of a nonlinearly stratified fluid past any arbitrary two-dimensional topography of finite extent You can download a recent version as a .zip file or get up-to-date version via the svn version (svn checkout svn://svn.code.sf.net/p/itides/svn/trunk itides-svn).

Matlab based scripting to set up, run and analyze groundwater model using (different versions of) MODFLOW (+SWI), MODPATH6, MT3DMS and SEAWAT.

This is a simple Octave script which calculates the frequencies/normal modes from an nwchem generated hessian matrix. The advantage of having a separate script for this is that you can use the same hessian to calculate frequencies for different isotopic substitutions i.e. you only have to run one nwchem calculation. The script is finished in its current form in the sense that it is feature complete. Feel free to amend, translate, copy, steal etc. See the README in the code repository for instructions. Installation: Simply download the file and start Octave in the download directory.
