Swarm highlights from first quarter of 2020


20 May 2020

Gravity Field Models from Swarm Data. A team of experts from five research institutions has exploited Swarm's onboard GPS receivers to measure temporal variations in Earth's global gravity field. Supported through Swarm DISC, the MAGF (Multi-Approach Gravity Field models) project team presented high-quality gravity field models from Swarm GPS data and published the results in the peer-review scientific journal Earth System Science Data DOI: 10.5194/essd-2019-158.This new approach does not only constitute an alternative and independent source of gravity data but also bridges the 10-month data-gap between the GRACE and GRACE-FO missions. 

A 3-day workshop on the VirES Virtual Research Environment (VRE) was held at DTU on 19-21 Feb 2020. The VRE platform allows users to access Swarm data and to analyse these data using own programs in Jupyter notebook sessions. The service also allows for upload of additional user data. The purpose of the workshop was to populate the VRE platform with ready-to-use notebook examples and to explore ways of making the service easy to use for new researchers.

Additional highlights includes: 21 peer-reviewed articles related to Swarm published or accepted for publication in the first quarter of 2020.

Swarm L1BOP v03.22 has been deployed in operation on 10 Feb 2020. This version of the processor has several improvements, including generation of 1Hz ASM data during ASM burst mode sessions; generation of PLASMA (Langmuir Probe) data during periods when magnetic data are not available, and generation of SC_xDYN_1B products when accelerometer Level 0 data are missing.

An improved approach for correcting the Swarm magnetic data for "Sun-related disturbances" has been developed and tested, and will be part of the next generation of L1BOP.
