Presentation Transcript

  1. GETG meeting Brussels, BE, November 2007 Status of GE-relevant activities at DMI Jurgen Watermann, Danish Meteorological Institute (DMI)

  2. Evolution of the naming of our group (last 10 years) Solar-Terrestrial Physics Division  Atmosphere Space Research Division  Geomagnetism and Space Physics Program  Division for Remote Sensing and Geomagnetism  ? ? ?

  3. Division for Remote Sensing and Geomagnetism Major activity: Remote sensing Minor activity: Geomagnetism primary activity: data collection, processing, validation probably negligible: use of the observations for research No activity: Space physics

  4. North Sea and surrounding land masses with observatories resp. calibrated variometers

  5. Greenland Magnetometers Dotted gridgeographic latitude and longitude Dashed linescorrected geomagnetic latitude (epoch 2000.0) Dotted line best-fit great circle (west coast stations) Blue circles DMI magnetometer stations Blue trianglesDMI geomagnetic observatories Blue Diamond Sondrestrom Research Facility Full circles data are transmitted to DMI in near real time regular letters (every 10-30 min, site depending) Full circles data from preceding day are transmitted italic letters to DMI via low-rate telephone modem Open circles data are stored locally and sent to DMI italic lettersvia snail mail (up to several months delay)

  6. Future directions • Establish a calibrated variometer station on Faroe • Develop further the commercial sector • (sale of instruments, data, derived products) • Increase external funding in geomagnetism • (through international cooperative projects)
