Swarm is the fifth Earth Explorer mission approved in ESA's Living Planet Programme, and was successfully launched on 22 November 2013.

The objective of the Swarm mission is to provide the best-ever survey of the geomagnetic field and its temporal evolution as well as the electric field in the atmosphere using a constellation of 3 identical satellites carrying sophisticated magnetometers and electric field instruments.

Swarm - B_NEC values fixed in a new set of corrected magnetic data

21 May 2015

A problem was found in the B_NEC values of the recently corrected Swarm magnetic data. For this reason, the MAGx_LR_1B products have been re-computed and made available again on the ESA FTP server in the "Current" folder.

Swarm Ionospheric Bubble Index and Field-Aligned Current products

14 May 2015

From 09 May 2015 the production of the Ionospheric Bubble Index (IBI) product has started, and the production of the Field Aligned Currents (FAC) derived from single spacecraft measurements has been restored.

Swarm Provisional Plasma Dataset: Caution recommended in using data from 13/01/2015 onwards

13 May 2015

From 13 January 2015 onwards, the Langmuir probe data (~/Advanced/Provisional_Plasma_dataset/Langmuir_Probes_Data) come without Flag>257 for the sweep mode timestamps. It is therefore difficult to identify and discard the sweep mode intervals.
