irfu-matlab is a package of matlab routines for space scientists working with data from different space missions.

irfu-matlab includes different parts:

    • General plasma physics: estimates of different plasma parameters, plasma wave dispersion relations, plasma wave visualization
    • General time series analysis routines: minimum variance, Hofmann-Teller, Walén analysis,...
    • Multi-spacecraft analysis methods: gradient methods (e.g. curlometer), timing
    • Data reading supports: Cluster Active Archive, OMNI, cdf
    • Plotting routines: time series, spectrograms, spacecraft location, (publishing quality figures!)

Download and installation.

Examples

All examples can be reconstructed directly after installing irfu-matlab and running the corresponding

routines.

It is also possible to run through a quick demonstration of irfu-matlab by simply running irf('demo')

Plasma physics

Cold plasma dispersion relation

Plasma wave movies

Dispersion surfaces can be plotted for different plasma parameters and colored depending on polarization, E/B, ellipticity...

Example shows shear Alfvén wave propagating at 45 degree angle. More examples

Cluster satellites

Cluster location

[c_pl_sc_conf_xyz]

Location can be shown in different formats - 2D, 3D, relative/absolute.


[Example_1]

Cluster separation during mission [Example_Cluster_separation]

Distance between two Cluster spacecraft is shown using the colors of both spacecraft
