NOC-1 BDY configuration tool
NOC-3 System support and Simplification work

NOC-1 - BDY configuration tool

Motivation: The ability for NEMO to be configured and run as a regional model with open boundaries forced with output saved from a wider area configuration is under-used due to the difficulty of preparing suitable boundary files. This task aims to contribute to the Configuration manager shared action by providing a high-level tool capable of completing all the necessary steps.
Status :
Main tasks :To produce an open source Python tool to configure open boundary (BDY) condition files for use with NEMO v3.4 onwards by transferring data from global NEMO simulations to defined regional domains. The tool will produce tracer/ice/dynamics (including tidal boundaries from TPXO7.2) BDY files. Written in Python this tool will be ready for integration into an all encompassing 'Configuration Manager' if desired.

NOC-2 - Eden and Greatbatch parameterisation

Motivation: The Eden and Greatbatch parameterisation (Ocean Modelling, 20,223-239) provides an eddy closure which is not purely dependent on local density gradients and leads to more realistic simulations with maximum EKE values towards the end of jets rather than near their origins. The expected result is a more realistic distribution of EKE with greater spreading away from generation sites.
Status :
Main tasks : Implement parameterisation; test and evaluate in ORCA1 and ORCA025 configurations with emphasis on the Gulf Stream separation region.

NOC-3 - System support and Simplification work

Motivation: The need for simplifying NEMO in preparation for next generation computer architecture work has been accepted by the NEMO community. The exact details of what is to be done and the timing and order of these changes has yet to be decided. NOC expects to take an active role in this process and reserves a substantial block of its annual contribution to ensure it can respond accordingly to the consortium plans. This block also covers routine system team work to respond to user initiated tasks (bug-fixes, requests for assistance, documentation etc.).

NOC-4 - Wetting and drying

Motivation: An option for supporting areas with wetting and drying properties (e.g. coastal applications with tidal forcing) has been under development for several years but has struggled to keep synchronised with wider code reorganisation. To avoid losing the capability it will be implemented in development branch which will track simplification changes so that it can be used by interested parties via the fcm_make facility for combining branches during the build phase.
