Power Spectral Characteristic of Martian Ionospheric Irregularities.
Abstract
The processed data relevant to the manuscript “Power Spectral Characteristics of MartianIonospheric Irregularities”. This repository consists of the Martian ionospheric ambient parametersaveraged for a 3-minute iterative window with a 2-minute overlap obtained from MAVEN’sionospheric passes below 400 km. Each ionospheric pass provides about 16-17 ambient ionosphericvalues, distinct in latitude, longitude, altitude, and local time. The dataset consists of spectral slope values and corresponding error along withthe maximum and minimum scale sizes of irregularities for the 3-minute window. This processed data is based on theelectron density measurements by Langmuir Probe and Wave (LPW), magnetic field observationsby fluxgate magnetometer (MAG), and derived key parameters from the MAVEN spacecraft for theperiod of 2014-2023. The original raw high-resolution data is available at https://pds-ppi.igpp.ucla.edu. The detailed description of the dataset parameters is given in the 'Description.pdf' file.
