• The polar middle and upper atmospheric tide can be affected by both electromagnetic disturbances from above due to ion drag or Juole coupling and by the various interactions due to polar vortex and wave dynamics in the denser lower atmosphere. The EISCAT radar system now includes mono-static UHF radar in Svalbard (ESR, 78°N) in the polar cap region, which complements the mainland KST system of both tri-static UHF and mono-static VHF radars in the auroral region of northern Scandinavia (67-69°N). It is expected that this radar system will play more important role in studying the Arctic upper and middle atmosphere dynamics. Here, a brief description of recent EISCAT tidal observations by the new ESR (EISCAT Svalbard Radar) is given.
