Results of ten rocket soundings conducted from Kronogard, Sweden, and Barrow, Alaska, during the summers of 1963 through 1965 indicate that a temperature of 150°K or less is a necessary but not sufficient condition for the existence of noctilucent clouds. Water vapor appears to be a critical ingredient in the occurrence of these clouds.
