Update on Swarm Field-Aligned Current Dual (FAC_AC) data issue

06 Jun 2022

As a follow-up of the news published on 23 November 2021 and on 16 December 2021, we want to update Swarm users about the issue affecting Field-Aligned Current Dual (FAC_TMS_2F) data: we can confirm that such data are affected by the reduced longitudinal separation between Swarm Alpha and Charlie consequent to orbits variations in the period from July 2021 to January 2022, and thus they are not scientifically meaningful.

For this reason, all FAC_TMS_2F data from 1 July 2021 to 18 January 2022 have been removed from the relevant folder in the Swarm dissemination server and will not be recovered.
