Science / project plan

Project description: 

We wish to improve the time latency, time resolution and the geographical coverage of geomagnetic measurements on the east coast of Greenland. To do that, we plan to install two new magnetometer stations in Daneborg and Kulusuk, with a time resolution of 1 second. DTU have geomagnetic measurements from Daneborg and Tasiilaq (near Kulusuk) in the period 1982-2006 and 1991-2014, respectively. We wish to continue the time-series for the locations.

The measurements are important for science and society, as it provides information on space weather in one of the most active region in the world, and thus enable us to develop space weather applications and improve our knowledge of space weather impacts in Greenland. 

Equipment description: 

  •  Fixed 3-axis FGE fluxgate-magnetometer  (built and designed by DTU Space, more information:
  •  1 Hz datalogger with 24 bit ADC (analogue-to-digital converter) and GPS (Global Positioning System)
  • A shield with stable foundation and weather proof box for magnetic sensor. Ruggedized box, either in- or outdoors, containing datalogger, magnetometer electronics, modem for mobile broadband network, power supply incl. batteries, remote control switch.

Project scedule:

  • May-June 2020: Specification, procurement and preparation of the equipment. 
  • August-September 2020: Travel to Kulusuk and Daneborg, installation of instrument (one week per station)
  • September 2020: data collection, calibration and distribution to the scientific community and to the ESA's Space Safety program.
