The Alomar Observatory
An eye to the middle atmosphere.
The Alomar Observatory is a facility at which groups of scientists from many nations investigate the Arctic atmosphere.



The observatory is host to a large array of active and passive instruments, such as radars, lidars as well as a digital imaging riometer.
Active Remote Sensing
  • RMR lidar, twin lidar 10 - 100 km. 1064 / 532 / 355 nm
  • Ozone lidar, 8 - 55 km, 308 / 353 nm
  • Mobile Fe lidar, remotely operated, 772 / 386 nm, doppler lidar
  • Troposphere lidar, five channel aerosol backscatter lidar, 0.5 - 18 km, 1064 / 523 / 355 nm
  • MAARSY, MST radar. 53.5 MHz, 4 - 20 km, 50 - 100 km
  • MF radar, 3.17 MHz, 50 - 100 km
  • Andenes Meteor Radar, 32.55 MHz, 80 - 100 km
 Passive Remote Sensing
  • Sun and moon photometer, CIMEL
  • Spectroradiometer( Brewer ) and UV - radiometer ( GUV )
  • All sky aurora imagers, filters for 557.7 nm and 630 nm
  • Advanced mesospheric temperature mapper, spectral range 1.5 - 1.65 µm
  • Imaging riometer, 38.2 MHz, 49 narrow beams
  • Geomagnetic activity monitor, two magnetometers
In-situ Sensing
NILU station for environmental monitoring, POPs and PFAS, Heavy metals and Hg.
All instruments combined, the Alomar Observatory is a fully equipped atmosphere laboratory in the Arctic.
