SW_VOBS_1M_2_

One-monthly time series of vector magnetic field values at fixed locations, on a uniform grid at satellite altitude

Thematic areas: Magnetic measurements

Applicable missions: Swarm

Applicable spacecraft: Swarm-A, Swarm-B, Swarm-C

Description

Such data, regularly distributed in space and time are suitable for modelling the main geomagnetic field, for core flow inversion studies, and for data assimilation studies of the core dynamo process.
