Objectives
• Upgrade and maintain a cutting-edge and verified ESM suitable for the national climate science community and participation in international model intercomparison projects.
• Provide an infrastructure for efficient model simulations, storage, analysis and validation available for the national climate science community and collaborating international groups.
• For efficient sharing of model data, provide an infrastructure that connects to international data grids and ensures that model data complies with established standards of the climate community.

Cost components
• Total cost plan for establishment and operation: MNOK 124
• Requested from RCN: MNOK 70• In-kind MNOK 54
• Payroll and indirect expenses MNOK 111• Other operating expenses* MNOK 13
*The main part of other operating expenses (MNOK 10) is cost of UNINETT Sigma2 computing and storage resources.

INES status and recent activities
• Kickoff meeting 13-14 September 2018.
• The planned starting point for INES was a finalized NorESM2 suitable for carry out CMIP6 experiments, but NorESM2 has been delayed for several reasons:
CESM2 finalization was delayed.
Calibration of NorESM2 has taken longer that anticipated.
Available HPC resources from Sigma2 have been lower than expected.
• Some WP1 and WP4 activities are delayed, while competence in WP3 and WP5 have been activated sooner than expected to aid NorESM2 finalization.

• Water isotopes in NorESM. Workshop on implementing water isotopes in NorESM arranged 29.11.2018 with Bjerknes staff. Contact with relevant CESM developers.
• NIRD Toolkit
• GitHub organization

• How to align with NCAR who soon completes the transition from a mixed subversion and github repositories to a unified Earth System Community Modelling Portal https://github.com/ESCOMP.
INES status and recent activities
Unified and “neutral” NorESM GitHub repository with Documentation, Issues, Teams etc.

CMIP6 status
• A NorESM1 based version will be used for the Decadal Climate Prediction Project while NorESM2 versions will be used for other MIPS.
• Configurations NorESM2-LM and NorESM2-MM show great improvements compared to NorESM1/CESM5 versions, but it has been challenging to achieve satisfactory energy balance while maintaining desirable simulation quality.
• We have experienced increased climate sensitivity compared to CMIP5 and a climate response that is very sensitive to details in the cloud parameterizations.
• The Sigma2 allocation period 2019.1 (April – September) is crucial in order to provide experiments relevant for AR6.

Interaction with new projects
• INES mostly consist of researchers with some of their time allocated for infrastructure work.
• Mutual participation in workshops/meetings.
• Find communication channels that facilitate both good internal and external communication.
