This handbook provides detailed descriptions of the Level 1b and Level 2 products. These products are derived from measurements from each of the Swarm spacecraft, as well as those from other spacecraft (so-called Multimission data) which are processed and delivered through the Swarm framework.

Level 1b products are lower-level and more directly related to the original measurements, after significant correction and calibration. Level 2 products are typically higher-level and present derived quantities and models. Some products draw on data from multiple spacecraft, and some from multiple missions as well as ground-based observations.

Explore the Catalogue to find information about each data product, or visit the main Swarm mission site to read more about the mission.
