Minimize 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.

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.

Corrected Swarm magnetic data now available

13 April 2015

As anticipated in January we are pleased to announce that a set of corrected Swarm magnetic data is now available.

Recovery of Swarm data gaps completed

10 April 2015

After the ASM on Swarm Charlie stopped its operations on 5 November 2014, the whole set of Level 1B magnetic data was not produced for that spacecraft. An improvement in the data processor has been recently introduced (for more details see the Swarm User Note) and the Level 1B magnetic data for Swarm Charlie based on the VFM instrument only have been recovered. The magnetic data coverage for Swarm Charlie is now complete.

New Swarm Level 1B data processor deployed in operations and Swarm Charlie magnetic data based on Vector Field Magnetometer available

27 February 2015

Since 24 February 2015, a new version of the Swarm Level 1B data processor has been deployed in operations. The most important feature to be noted is the capability to generate magnetic Level 1B products based on Vector Field Magnetometer inputs only, in order to cope with failures of the Absolute Scalar Magnetometer, as occurred on 5 November 2014 on Swarm Charlie.

Swarm's precise sense of magnetism

07 May 2014

Although they were launched only five months ago, ESA's trio of Swarm satellites are already delivering results with a precision that took earlier missions 10 years to achieve.
