2. © Crown copyright Met Office Scientific Projects Cirrus ice clouds: Microphysics and Satellite retrieval validation. Mixed-phase: Microphysics and cloud evolution. Clear-sky: Humidity and chemistry. A wide-range of science objectives are to be investigated. The specific flight sortie will be chosen depending on the weather conditions and instrument status on a daily basis. Fit around DIAMET observing period.

Includes ice particle density, diffusional growth, aggregation and sedimentation (and ISMAR testing). Operate in Southwest/Northwest-approaches. VACAR (Tom Emmery/Stephan Havemann): Cirrus optical properties. IASI (METOP) overpass. COSIC (Jim Heywood): Persistent contrail formation. MSG.
