| Abstract | The magnetic field is a crucial quantity to measure in order to characterise the solar wind and understand the physical processes that control its dynamics. The Solar Orbiter mission (SolO) employs two magnetometers: 1) The MAG instrument which uses two fluxgate magnetometers to provide the solar wind magnetic field from DC to several tens of Hz without spacecraft perturbations, and 2) the SCM (Search Coil Magnetometer) instrument, which is part of the RPW suite and measures the fluctuations of the magnetic fields from typically 1 Hz to 50 kHz. In order to ease the analysis of the magnetic field over a wide range of frequencies for the scientific community, we have built a merged data product that takes the best of the two instruments and provides the magnetic field from DC to 256 Hz or 4096 Hz. We will describe how it is produced and distributed, and discuss its advantages and caveats. |
| Description |
This dataset combines the Solar Orbiter MAG magnetometer and SCM (Search Coil Magnetometer) data. The MAG
instrument is a high-performance dual fluxgate instrument with data rates up to 128 vectors/s, while the
SCM measures fluctuations of magnetic fields from 1 Hz to 50 kHz. The combined dataset offers
comprehensive magnetic field measurements, crucial for studying solar wind and space plasma phenomena.
Extensive cleaning of the MAG data removes artificial signals, resulting in high-quality Level 2 data
files. SCM data complements this with higher frequency measurements. Both datasets provide critical
insights into interplanetary magnetic fields and space weather.

| Mission Description | Solar Orbiter is a mission of international collaboration between ESA and NASA. It explores the Sun and the heliosphere from close up and out of the ecliptic plane. Launched on 10 February 2020, it aims to address the overarching science question: how does the Sun create and control the Heliosphere – and why does solar activity change with time? To answer it, the Solar Orbiter spacecraft is cruising to a unique orbit around the Sun, eventually reaching a minimum perihelion of 0.28 AU, and performing measurements out of the ecliptic plane: reaching 18° heliographic latitude during its nominal mission phase, and above 30° during its extended mission phase. It carries six remote sensing instruments to observe the Sun and the solar corona, and four in-situ instruments to measure the solar wind, its thermal and energetic particles, and electromagnetic fields.
