A case study of a sporadic sodium layer observed by the ALOMAR Weber Na LIDAR
S.1071-1081 Several possible mechanisms for the production of sporadic sodium layers have been discussed in the literature, but none of them seem to explain all the accumulated observations. The hypotheses range from direct meteoric input, to energetic electron bombardment on meteoric smoke particle...
