Optical model of noctilucent clouds based on polarimetric measurements from two sounding rocket campaigns

Abstract: Two Nike-Apache payloads were launched into noctilucent cloud (NLC) displays from Esrange, Sweden in the summer of 1971 and two in the summer of 1973. A two-color photopolarimeter was part of the multiexperiment payload that included the Pandora collector of Dudley Observatory. The absolute brightness and degree of polarization are used to determine the size and number density of NLC particles. The Pandora collection size distribution and two arbitrary size distributions of ice, iron, and nickel are compared w… Show more

“…Data from two rocket flights into PMCs with a polarimeter having four separate spectral channels at 214, 366,453 and 536 nm (Witt, 1967) 5 were analyzed by Heintzenberg and Wia, 19786 indicating no ice particles above about 60-75 nm. Tozer and Beeson (1974) 7 obtained polarimetric data of PMC in three separate rocket flights, with channels at 410 and 540 nm. They obtained an upper limit on particle size of about 120 nm.…”
