    • Retrieval of sodium number density profiles in the mesosphere and lower thermosphere from SCIAMACHY limb emission measurements 

      Langowski, M.P.; von Savigny, C.; Burrows, J.P.; Rozanov, V.V.; Dunker, Tim; Hoppe, Ulf-Peter; Sinnhuber, M; Aikin, A.C. (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-01-28)
      An algorithm has been developed for the retrieval of sodium atom (Na) number density on a latitude and altitude grid from SCIAMACHY (SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY) limb measurements of the Na resonance fluorescence. The results are obtained between 50 and 150 km altitude and the resulting global seasonal variations of Na are analyzed. The retrieval approach ...
