Minimize Swarm Operational News

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.

First release of Swarm L2 precise orbit products

18 February 2015

A first set of L2 precise orbits has been released. The products cover the period from launch to the end of 2014 for all Swarm spacecraft.

Swarm Preliminary Plasma Dataset released

05 February 2015

Swarm plasma data is now available to the science users thanks to the efforts of the Swarm Electric Field Instrument (EFI) principal investigators and their teams. Due to thorough calibration activities on the instruments and the processing algorithms evolutions still ongoing to achieve the best possible data quality, this plasma dataset is a work in progress and can be considered as preliminary.

Swarm L1b data regenerated from 2 to 17 January 2015

28 January 2015

Due to a problem in the L1b data processor leading to wrong rotation angles and, therefore, accuracy degradation on magnetic data, Swarm data with baseline 03 and file counter 02 produced from 2 to 17 January were not correct.

The 12th Generation International Geomagnetic Reference Field (IGRF)

21 January 2015

IAGA has released the 12th generation International Geomagnetic Reference Field (IGRF). The IGRF is a series of standard mathematical models describing the large scale internal part of the Earth's magnetic field between epochs 1900 A.D and present. Data from ESA's Swarm satellite mission were crucial to the development of IGRF-12.

Swarm Level 2 Field Aligned Currents products temporarily unavailable

21 January 2015

Due to a technical issue within the Field Aligned Currents (FAC) processor, FAC products are currently not produced and, therefore, not distributed, since 1 January 2015 (included).

Upcoming Swarm data release

15 January 2015

As a key priority of the Swarm mission, the last few months have seen many cal/val teams involved in the validation of the products and the assessment of the observed data quality issues as reported here.

Following these activities, an updated version of core data products will soon be provided to the user community.

Swarm GPS, ORBIT and ATTITUDE products regenerated

19 December 2014

Following recommendations by the Swarm Quality Working Group, the GPS, ORBIT and ATTITUDE products (file types GPSxNAV_1B, GPSx_RO_1B, GPSx_RN_1B, MODx_SC_1B, STRxATT_1B) have been regenerated since the beginning of the mission up to 19 October 2014.

Swarm celebrates one year in orbit

24 November 2014

One year ago, on 22 November 2013, Swarm was launched and started its highly successful mapping of the Earth's magnetic field, electric field and other geospace parameters. We celebrate the mission's first birthday and wish the trio of satellites a long and healthy life in the service of science.

Improved Swarm Data Access completed

14 November 2014

As previously announced on 20 October 2014, the new FTP layout for the Swarm dissemination server was deployed on 11 November as planned.

ASM anomaly on Swarm C satellite

07 November 2014

The Absolute Scalar Magnetometer (ASM) A Unit on the Swarm Charlie spacecraft has been off since 19:37 on 05 November 2014.

Improved Swarm Data Access - reminder

06 November 2014

Following feedback from different user teams, the Swarm Mission Team has decided to improve the Swarm FTP dissemination server to better handle the fact that in the future the L1 and L2 Product Baselines may evolve separately per processor and per satellite depending on the improvements of the algorithms and the instruments' calibration.

This is to remind the Swarm data users that the FTP server layout change will be effective on Tuesday 11 November 2014, when the old directory structure will be replaced by the new one.

Swarm GPSR updates

22 October 2014

Following recommendations by the Swarm Quality Working Group, modifications have been implemented to the GPSR instrument and its data.

Improved Swarm Data Access

20 October 2014

Following feedback from different user teams, the Swarm Mission Team has decided to improve the Swarm FTP dissemination server to better handle the fact that in the future the L1 and L2 Product Baselines may evolve separately per processor and per satellite depending on the improvements of the algorithms and the instruments' calibration.

Swarm Field Aligned Current (FAC) data - service restored

20 October 2014

The Field Aligned Current (FAC) production on all of the Swarm satellites has been successfully resumed.

Swarm Field Aligned Current (FAC) data unavailability

14 October 2014

The Field Aligned Current (FAC) production on all of the Swarm satellites is temporarily interrupted.

Swarm C: VFM instrument off for approximately 24 hours

26 August 2014

The Vector Field Magnetometer on the Swarm C satellite was temporarily switched off from 05:52 UTC on 25 August 2014, until 11:25 UTC on 26 August 2014.

Complete Swarm orbit manoeuvre information available

06 August 2014

As of today the complete list of orbit manoeuvres of all three Swarm satellites is available for download by the user community.
