What is Swarm?
Swarm is the fifth Earth Explorer mission approved in ESA's Living Planet Programme, and was successfully launched on 22 November 2013.
As part of the Third Party Missions programme, the e-POP instrument of the Canadian Space Agency's CASSIOPE mission joined the constellation in February 2018.
The research objectives 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.
Mission Operations News
The non-gravitational acceleration and thermosphere density data, both derived from the GPS receiver data, were reprocessed for the entire period from launch in November 2013 until July 2019 for all three Swarm satellites.

A new baseline of the Equatorial Electric Field (EEFxTMS_2F) L2 product was released on 4 September 2019. This product contains the eastward Equatorial Electric Field (EEF) estimated from magnetometer measurements of each Swarm spacecraft as they cross the magnetic equator.
Mission Scientific Highlights
15 May 2019
As far as we know, Earth's magnetic north has always wandered, but it has recently gained new momentum and is making a dash towards Siberia at a pace not seen before. While this has some practical implications, scientists believe that this sprint is being caused by tussling magnetic blobs deep below our feet.
The constant improvement in the strategies to operate the two Thermal Ion Imagers (TII) sensors on-board each Swarm spacecraft, defined by scientists and engineers in dedicated monthly TII anomaly review board meetings, allow a significant increase in TII data coverage, and a substantial improvement in TII data quality.
The Call for Ideas for Swarm "New data products and Services" closes on the 30th of June 2019.
For more information about the call can be found on the DTU.dk website.
The eighth Swarm Data Quality Workshop was held at ESRIN (Frascati, Italy) from 8 to 12 October 2018. This workshop was instrumental in addressing the processing and use of Swarm data and defining a road map for the future.
