Swarm Operational News
03 September 2015
New Swarm Level 2 Cat-2 data are available starting from 27/08/2015. Field-Aligned Currents (FAC), derived from both single and combined spacecraft data are again available, and Equatorial Electric Field data (EEF) are also now available.
24 August 2015
The Langmuir Probe preliminary dataset, containing ionospheric electron density and temperature, have been updated for the three Swarm spacecraft up to 18 August 2015.
22 July 2015
From 18 July 2015, changes in the Swarm data processing have been introduced.
Key points: magnetic products corrected by the scalar residuals are now directly computed by the operational processor; EFIx_PL_1B are generated directly from the operational processor and can be accessed in the Current folder.
09 July 2015
The new Swarm Orbit Counter auxiliary data file is now available on the Swarm dissemination server in the directory: Auxiliary/Sat_x/AUXxORBCNT
01 July 2015
As announced at the IUGG General Assembly 2015, the first official Swarm core field models were released. In addition, the Swarm magnetospheric field model from the comprehensive inversion as well as the 1D model of mantle conductivity and 1D C-response maps were released.
01 July 2015
The GPSR settings on the Swarm C satellite were changed on 6 May 2015 in order to further improve the receiver performance:
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.
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.
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.
13 May 2015
The GPSR antenna field of view was increased in steps to 88 degrees on the Swarm C satellite in order to find the optimal setting. Following the analysis of the GPSR performance on Swarm C, the antenna field of view has been increased to 88 degrees also on the other Swarm satellites.
The L2 precise orbit products now cover the period from launch to 31 March 2015 for all Swarm spacecraft. Two types of orbit products are available:
As already reported here, a set of Swarm magnetic data corrected from external disturbance effects was made available in a dedicated area of the ESA FTP server two weeks ago.
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.
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.
