Possible artefacts in Swarm Field Aligned Current Dual s c FAC AC product

09 Mar 2022

Due to the recent manoeuvres to modify the orbits of Swarm-A and C, positioning them in an almost identical orbit during the counter rotating phase the current density estimates from Field-Aligned Current Dual s/c data product (FAC_AC) has been affected by a number of artefacts during last months. 

ESA is currently working on improvements for the FAC_AC L2 algorithm in order take into account of this different orbital configuration, and calculate a more reliable current density estimate from the data measured by the lower pair.
