| CHAOS-8 |
The CHAOS-8 - A model of the time-dependent near-Earth geomagnetic field between 1999 and 2025. CHAOS-8 is based on magnetic field observations collected by the low-Earth orbit satellites Swarm, MSS-1, CSES, CryoSat-2, CHAMP, SAC-C and Ørsted, and on annual differences of monthly means of ground observatory measurements. |
