Identifying the enigmatic Haystack and HASP ice clouds observed by CIRS in Titan's stratosphere
Abstract
Stratospheric ice clouds have been repeatedly observed in Titan's atmosphere by the Cassini Composite InfraRed Spectrometer (CIRS) since the Cassini spacecraft entered into orbit around Saturn fourteen years ago. However, their chemical composition is still undetermined. For some of them, co-condensation could be a formation mechanism. We present the laboratory experiments we have conducted and the results we have obtained with the aim to identify particularly two perplexing observed stratospheric clouds, the Haystack and the High-Altitude South Polar (HASP) ice clouds.
