    • Change in turbopause altitude at 52 and 70° N 

      Hall, Chris; Holmen, Silje Eriksen; Meek, Chris; Manson, Alan; Nozawa, Satonori (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-02-26)
      The turbopause is the demarcation between atmospheric mixing by turbulence (below) and molecular diffusion (above). When studying concentrations of trace species in the atmosphere, and particularly long-term change, it may be important to understand processes present, together with their temporal evolution that may be responsible for redistribution of atmospheric constituents. The general ...

    • A new five-wavelength photometer operated in Tromsø (69.6°N, 19.2°E) 

      Nozawa, Satonori; Kawabata, Tetsuya; Hosokawa, Keisuke; Ogawa, Yasunobu; Tsuda, Takuo; Mizuno, Akira; Fujii, Ryoichi; Hall, Chris (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-11)
      A new fve-wavelength photometer was developed and installed at the EISCAT Tromsø site (69.6°N, 19.2°E) in January 2017. The photometer consists of two units: an optical unit and a control unit together with a PC. The photometer is capable of simultaneously observing auroral emissions with fve wavelengths. A uniqueness of the present system is its capability of precise pointing, which enables ...
