ICCARE

The ANR ICCARE project (Ice Crystals in deep convective Clouds: interaction with Aerosols, Radiation and Electricity; https://anr.fr/Project-ANR-21-CE01-0006, 2022-2026) aims to better understand how ice crystals interact with aerosols, cloud microphysics, atmospheric electricity, radiation and dynamics, and how these interactions control the evolution of deep convective systems. ICCARE is based on coupled numerical modeling activities with the Meso-NH community atmospheric model, and exploitation of space observations and existing measurements collected during past campaigns (FP7 HAIC, ANR EXAEDRE).

Project objectives

• characterize the formation, growth and dissipation of ice crystals in the convective, stratiform and cirriform regions of deep convection systems, using existing observations and numerical simulations
• develop a complete and consistent cloud physics numerical module in a resolved cloud model
• determine how ice crystal properties control the macroscopic characteristics of deep convection clouds (duration, precipitation, cloud top height, etc.).

As part of this project, the AERIS/SEDOO center is involved in the following ways:

• Provision of a website
• Provision of a catalog to distribute the project data.
