Abstract
The objective is to develop a next-generation model of the interaction of aerosol with mixed phase cloud dealing with key processes much more explicitly than is presently possible. It is proposed to develop the model based on the latest version of the Met Office Cloud Resolving Model (CRM) and to utilise the range of detailed aerosol models being developed through DIAC.
The model will be a tool for exploitation within and enhancement of the successful APPRAISE consortium in the clouds area. The new model will also be a tool for the development of aerosol-ice/ mixed phase cloud treatment in UKCA.
The specific milestones within the project will be:
- To produce a new state of the art parcel model with explicit microphysics capable of being driven by observed dynamics or dynamics calculated from the CRM (start August 2006, delivery July 2007, with continued development to the end of July 2009). This model will be used to guide development of the CRM and test the end product model (Years 2 and 3)
- To improve the parameterisation of cloud microphysics using the 2 and 3 moment scheme within the Met Office Cloud Resolving Model (start August 2007, delivery July 2008)
- To produce a CRM with Explicit bin Cloud Microphysics with improved treatment of the aerosol and microphysics (start August 2006, delivery July 2009)
