The Earth Clouds, Aerosol and Radiation Explorer (EarthCARE; hereafter, ECARE) is a joint European/Japanese (ESA/JAXA/NICT) mission. 94GHz-Doppler cloud profiling radar, high spectral resolution lidar (HSRL) operated at 355 nm, multi spectral imager and broad band radiometer will be employed. The combination of these instruments will provide three-dimensional distributions of clouds with vertical motion, aerosols, and precipitation and their radiative characteristics.

In this workshop, we first introduce ECARE to modelers: What's new with ECARE, and what are major physical quantities to be derived from ECARE. Then, we plan to have discussions on the following key topics in this workshop.

• Evaluation/improvement of cloud/convection/aerosol processes of models through ECARE observations.
• Key questions/issues arising from Global Storm Resolving Models:
  Lessons from DYAMOND and new initiatives.
• Key questions/issues arising from GCMs or climate modeling:
  Uncertainties of GCMs related to clouds/convection. Lessons from past COSP analysis on CMIP models and new initiatives.
• Analysis:
  Talks on topical analysis studies will be encouraged, including new research initiatives using Doppler cloud radar: e.g. global view of vertical motions/mass flux.
• Satellite simulators:
  Overview of existing satellite simulators and tasks for analysis of ECARE using simulators
• Assimilation:
  Assimilation is a significant part of the satellite-modeling collaboration. In this workshop, overviews of assimilation activities related to ECARE will be introduced. Technical details will be discussed in a separate assimilation meeting in the future. New ideas of assimilation, such as parameter estimation, might be covered.
• Introduction to forthcoming field campaigns in support of ECARE and modeling collaborations.
• Discussions on sciences connected to NASA/AOS (or ACCP), which is planned for launch around 2030, including possible collaborations with EarthCARE.

Main theme: How can models and ECARE collaborate? Specifically

• How to evaluate/improve models by ECARE data?
• What are the major issues/biases of models in representations of cloud, convection, precipitation and aerosols?
• Process understanding: cloud, precipitation, convection, radiation and their coupling.
• New research areas/subjects arising from ECARE.
