We are pleased to announce that the reprocessing of Swarm L1B orbit, attitude and magnetic field data carried out to replace the degraded data for the time period from October/December 2018 to 24 August 2023 has been completed.

The new OPER data are being published on the Swarm Dissemination server with increased product baseline and file counter (0504 for orbit and attitude products, 0605 for magnetic data) and the old data version is being removed. 

We would like to remind users that the previous version of L1B data was affected by the following issues:

• Degradation of attitude data during STR operations at 2 Hz sampling rate for the period from October/December 2018 to 24 August 2023
• Issue with B_NEC magnetic data for the period from 24 June to 24 August 2023

Also, since in the last version of the L1B processor an updated internal library has been used that improved parameter precision, the reprocessing has been extended from 25 August 2023 to 19 May 2024, in preparation for the upcoming Transfer To Operations of the new improved algorithm that will be performed in the next few days.

Please note that the dissemination activity is still ongoing and the dataset will be fully available in a few days.
