Ice Particles Observed in a Cirriform Cloud at −83°C and Implications for Polar Stratospheric Clouds

Abstract

Mesurements obtained in a thin, cirriform cloud that formed in the temperature range of −83° to −84°C and an altitude range at 16.2 to 16.7 km are presented. Implications of the results for particle generation in polar stratospheric clouds developing with similar conditions are discussed.
