  1. Magnetic field gradients from the ST-5 constellation: Implications for Swarm And more than a few words on new work on the magnetic field of our moon, with possible terrestrial applications Michael Purucker, Raytheon @ GSFC/NASA With a cast including Terry Sabaka, Jim Slavin, Guan Le, Robert Strangeway, and Cathy Busby GFZ-Potsdam Special thanks to Martina, Vincent, Hermann, Yoann, Monika, and of course Mioara 16 Oct 2007

  2. Swarm and ST-5 compared Similarities Differences

  3. Implications for Swarm • Lithospheric field science possible without precise pointing knowledge (Swarm failure case) • Solar minimum conditions enabled science. • The higher resolution brings into focus many more geologic features (e.g. Rio Grande rift, Gulf of California). • ST-5 data available on the Web. Useful for technique development and further interpretation, especially if coupled with ephemeris improvements. • http://core2.gsfc.nasa.gov/research/purucker/st5_gradients.html and Purucker et al., Magnetic field gradients from the ST-5 constellation: Improving magnetic and thermal models of the lithosphere, GRL, in press

  4. Development of a novel, correlative technique, with lunar and possibly terrestrial applications • Space domain equivalent to harmonic correlation technique of Langel (1995), allowing for the isolation of a primary signal in the presence of interfering signal. • Enhanced because it allows for the inclusion of multiple vector components, and altitude normalization.

  5. Thank you, GFZ!
