Description

This is a high-level data product based on particle and magnetic-field measurements taken by the Ion Mass Analyser (IMA) and Magnetometer (MAG) instruments, respectively, onboard the European Space Agency’s (ESA’s) Venus Express (VEX) mission. VEX orbited Venus between 2006-2014 collecting data on the plasma environment around the planet for a wide variety of space physics studies. IMA is an ion mass-energy spectrometer from which plasma bulk parameters can be calculated. MAG measures the three components of the background magnetic field.

The dataset contains proton bulk densities, speeds, and temperatures (perpendicular and parallel to the magnetic field) measured by IMA at 1181 spatial locations in Venus’ dayside magnetosheath. The concurrent average magnetic-field strength measured by MAG accompanies each set of proton parameters. Additionally, medians of the same parameters measured in the upstream solar wind (SW) during each orbit are included (but not the individual measurements from which the medians are calculated). The location of VEX during each measurement is provided in the Venus
