An Integrated Nonlinear Analysis (INA) Software for Space Plasma Turbulence

We built an integrated nonlinear analysis software (INA)-designed to study space plasma turbulence and intermittency. The MATLAB programming environment was used for the algorithmic development implementation of methods spectral analysis, multiscale fluctuations multifractal analysis. performance INA is demonstrated using magnetic field measurements during inbound pass through Earth's magnetosheath region Cluster 3 spacecraft. show how specific features power density can be mapped localized time-frequency regions in spectrogram representation, identify multiple intermittent events wavelet-based local intermittency measure. Multiscale probability functions showed clear departures from Gaussianity, signifying presence Structure rank-ordered revealed nature analyzed signal. freely distributed as a standalone executable file any interested user, provides integrated, interactive, user-friendly which one import data set, customize key parameters, apply on same signal then export high-quality, publication-ready figures. These are only few many distinguishing INA.
