Data, Innovation, and Science Cluster Multi-mission synergies are highly beneficial! New opportunities by multi-mission MAG (workshop, special issue, recommendations): • Core field modelling • Ionospheric and FA-currents • magnetospheric currents • Mantle induction studies • … New opportunities by multi-mission GPS: • Long-term evolution of plasma content • altitude information on electron content ionosphere/plasmasphere • Gravity field modelling • … • • • In support for Swarm? Enabled by Swarm? Totally new and/or stand-alone opportunities from other (non-Swarm) missions? • What causes the enhanced exploitation? : amount of data, data quality, enhanced LT-coverage, enhanced altitude coverage, … 9 th SDQW 17 -20 September 2019 3 / 5 Prague, Czech Republic

Data, Innovation, and Science Cluster Swarm and Multi-mission 33. Structure a “Magnetometer calibration Done/Ongoing A dedicated workshop has been conducted on May 21 Synergies expert group” and organise a workshop on -23, 2019 in Potsdam, Germany. A special issue is “Multi-mission data calibration and open in EPS: application” (about 6 month after the https: //www. springeropen. com/collections/leo SDQW#8) for identification and coordination of the multi-mission potential 33 a and corresponding formulation of needs Issue a consolidated recommendations and procedures. 34. Prepare and provide Cryo. Sat and Goce L 1 B Done/Ongoing Fully calibrated Cryosat-2 magnetic data for August data to the scientific community, consisting 2010 to December 2018 available as daily CDF files at in daily CDF files (time, position, calibrated Swarm PDGS 34 a BFGM, STR data, BNEC, flags, …) before (ftp: //swarm-diss. eo. esa. int/%23 Cryo. Sat-2) Living Planet (May 2019) Peer-reviewed article to be submitted to EPS special issue is in preparation. 35. Make a peer-review publication describing Ongoing An article describing data product and calibration processes of magnetic LEO data is expected to be a contribution of the special issue with submission 33 b deadline in 2020: closed 34 b 38 a https: //www. springeropen. com/collections/leo First results presented at IUGG in July 2019 and at Swarm DQW #9 Same status as [Req. 36] (in case “long term modeling” concerns “modeling of the geomagnetic field”) 36. Use Cryo. Sat-2 dataset for gap between Done CHAMP and Swarm 37. Use GOCE, GRACE, Cryo. Sat-2 and in a joint Ongoing modelling, calibration, alignment process with Swarm and CHAMP for consistent long term modelling. 38. Enhance the potential synergy between Done/Ongoing GOCE TEC data is openly published at http: //eo. Swarm and GOCE thermosphere - virtual-archive 1. esa. int/GOCE-Thermosphere. html, ionosphere data. first results were presented at DQW#8. Synergies between Swarm and Sentinels TEC presented at Swarm DQW #9. 9 th SDQW 17 -20 September 2019 4 / 5 Prague, Czech Republic

Data, Innovation, and Science Cluster Swarm and Multi-mission 39. Enhance the potential synergy between Ongoing Synergies Swarm and GRACE(-FO) and make accessible well-validated and documented products, with similar standards as for Swarm and 33 b/38 b GOCE. Closed 9 th SDQW 40. Foster cooperation and exchange experience Done between ACC data processing experts from GRACE-FO & Swarm missions 41. Develop multi-mission, consistent, reliable Open and well-calibrate multi-mission datasets to address key scientific challenges related to upper atmosphere “climate” trend analysis, studies of longer term secular variation vs solar cycle effects, quantification of energy transports by waves and other phenomena. 17 -20 September 2019 GRACE magnetic data quality has been found not being high enough for high level products (noisy, cut at 50 kn. T). GRACE-FO data available since summer 2019. C. Siemes analyzed a sample dataset from GRACE-FO and provided feedback in form of a document to the GRACE-FO team. Topics may potentially be addressed in 4 D-ionosphere and/or new DISC ideas. Evaluation pending. 5 / 5 Prague, Czech Republic
