1 Hz Swarm on track values of observed, external and projected vector geomagnetic field¶
In situ time series of vector geomagnetic field derived from the Swarm constellation at 1 second cadence from 1 January 2014 to 31 December 2020. The output is a single .txt formatted file for each of the 3 satellites of the Swarm constellation, each of one has a size of about 14.5 GB. The sample file attached is extracted from one month of data acquired by Swarm A
