Presentation Transcript

  1. GFZ, DTU and the Swarm ESL Consortium • Presentation of GFZ, Department 2.3 Earth’s Magnetic Field • Presentation of DTU, Division of Geomagnetism • The Swarm ESL consortium Virtual Workspaces for EO Scientists - VIRES Teaming Meeting @ GFZ Potsdam, 5 November 2013

  2. Structure of GFZ

  3. GFZ Section 2.3 „Earth Magnetic Field“ Modelling of the Earth Magnetic Field Thermosphere/Ionosphere/Magnetosphere Magnetic Ground Stations / Niemegk Satellites – CHAMP / Swarm Observations

  4. International network of geomagnetic observatories

  5. CHAMP – satellite mission Bild von Matthias mit wind über pole GFZ 2000 – 2010 Data series: magnetic field, eletron density, electron temperature, neutral density and wind

  6. DTU Space

  7. Magnetometer development Division of Geomagnetism • Geomagnetic observatories and data • Directional drilling • Space physics / space weather • Swarm • Swarm L2 data products • Geomagnetic Field Modeling • Probing Earth’s interior

  8. Ørsted – a trendsetter • ØrstedFirst “modern” geomagnetic satellitesmall-satellite, dedicated mission to measure B650-850 km altitudeFebruary 1999 -still operating, after > 14 years in space! • CHAMPlow altitude (400-450 km)July 2000 – Sept 2010 • SAC-CCopy of Ørsted experiment • All thee satellites (and Swarm!) carry similar instruments (vector magnetometerand star imager from DTU Space)

  9. Magnetic Ground Observatories DTU station5 observatories15 variometer stations DTU instruments250 sold in 20 years DTU hosts WDC for Geomagnetism- unique holding of analog recordings- calculation of PCN index

  11. Swarm Constellation of 3 satellites to investigate the Earth’s magnetic field • ESA’s Fifth Earth Explorer Mission • Proposed by a European consortium led by • EigilFriis-Christensen (DTU, DK) • Hermann Lühr(GFZ, D) • Gauthier Hulot(IPGP, F) • Based on experience with Ørsted (DTU) and CHAMP (GFZ), both regarding satellite design, instruments, data processing and scientific exploitation • Launch scheduled for 22 November 2013

  12. Swarm Constellation of 3 satellites to investigate the Earth’s magnetic field • SCARF consortium: development of the Level 2 Processing System SCARF: six European institutes and two US partners • Distributed data processing facility • Six processing chains, spread all over Europe, processing L1b data from the Swarm satellites and delivering the products to ESA for distribution to the scientific community • Swarm ESL – the continuation of the SCARF development into the exploitation phase, extended with L1b responsibility • Consortium with 10 subcontractors: All members of the SCARF consortium + three more. Start Nov 2013, end mid-2018 • Responsibility for the maintenance and evolution of the Level 1b processors • Responsibility for the operation of the processing chains, the quality and overall scientific value of the products – and also for the evolution of the processing chains to meet the needs of the scientific community

  13. DTU Space, relevant experience DTU Space has taken active part in approximately 15 satellite missions in the past. • DTU Space is currently engaged in the ESA Integral mission, the Danish satellite Ørsted, • the Argentine/US satellite SAC-C, • the German satellite CHAMP and the • ESA Swarm mission, for which DTU Space is the Prime Contractor for the Development of the Swarm Level 2 Algorithms and Associated Level 2 Processing Facility (L2PS) The scientific heritage of DTU Space in the field of geomagnetic research has aggregated from more than 15 years of experience with the exploitation of data from these research satellites

  14. SCARF and Swarm Satellite Constellation Application and Research Facility (SCARF) is a consortium, comprising • British Geological Survey (BGS) • DTU Space – National Space Institute (DTU) • Delft Institute of Earth Observation and Space Systems (DEOS) • Helmholtz Centre Potsdam - German Research Centre for Geosciences (GFZ) • EidgenössischeTechnischeHochschule Zürich (ETH) • Institutde Physique du Globe de Paris (IPGP) with additional contributions from • NASA Goddard Space Flight Center (GSFC) • University of Colorado (CIRES) • Charles University Prague (CUP)

  15. DTU Space, relevant experience, cont’d DTU Space has been awarded the contract for the SwarmESL project as the Prime Contractor. The objectives are • Processing of Level 1b data into Level 2 products (Cat-1) • Support to operation and performance evaluation (Cat-2) • Maintenance and evolution of all Level 2 algorithms • Maintenance and evolution of Level 1b algorithms …and to currently monitor the quality and propose improvements of the scientific value of the Swarm products.
