© 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.

© Crown copyright Met Office Cirrus: Ice-phase physics CIRRUS (Richard Cotton): Ice particle properties in deep altostratus/cirrostratus and cirrus uncinus. 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.

© Crown copyright Met Office Mixed-phase and liquid clouds ICEPIC2 (Phil Brown): Evolution of precipitation in convective clouds around the UK, especially the initiation and evolution of ice-phase particles and their relationship to aerosol inputs at the cloud base. NU-WAVE (Richard Cotton): Ice heterogeneous nucleation, diffusional growth and evaporation in altocumulus lenticularis. CHIMPS (Paul Barret): The structure of clouds and humidity in the mid- troposphere across various spatial scales. COALESC (Steve Abel): Stratocumulus evolution.
