This repository contains ionospheric F region in situ data analyzed for the article: "Structural characterization of the equatorial F region plasma irregularities in the multifractal context", Neelakshi J., Reinaldo R. Rosa, Siomel Savio, Esfhan Alam Kherani, Francisco Carlos de Meneses, Stephan Stephany, and Muralikrishna P., submitted to the journal: Annales Geophysicae (ANGEO) Zip folder Data_Files_ANGEO contains two folders: 1) Rocket_Experiment1_Dec1995: This folder contains six time series chosen from the rocket experiment performed on December 18, 1995 from rocket launching station Alcantara, Brazil. All six time series are named with their corresponding mean height. All time series are of electric field fluctuations. 2) Rocket_Experiment2_Dec2012: This folder contains six time series chosen from the rocket experiment performed on December 8, 2012 from rocket launching station Alcantara, Brazil. All three time series are named with their corresponding mean height. All time series are of electron density fluctuations. for example: timeseries_264.58km.txt has electric field fluctuations measured around mean height of 264.58 km.
