NOC-1 - Reimplement Smagorinsky

Motivation: The rationalisation of the LDF operators offers the possibility of cleanly reintroducing the Smagorinsky parameterisation by adding an appropriate subroutine to set the three-dimensional coefficient array that already exists. This should represent an additional improvement over the previous implementation in that it will work with both harmonic and biharmonic operators.

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 verification work

Motivation: The need for simplification work carried out in preparation for next generation computer architecture work has meant wholesale streamlining and reorganising of the code. More in-depth testing of features key at medium to high resolutions is required to confirm that code integrity has been maintained. Testing will need to be performed at the global scale (at least ORCA025) and will include verification of: 1. Full ice embedding options (LIM3 and CICE, subject to resources) 2. Robustness of the Z-tilde coordinate 3. Appropriate use of the ICB module. 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 needs. This block also covers routine system team work to respond to user initiated tasks (bug-fixes, requests for assistance, documentation etc.).

NOC-4 - Reference manual update for v3.6 stable

Motivation: With the main focus for the system team on future releases there is the danger of the reference manual for v3.6 stable falling into disrepair. With most CMIP6 work relying on this version there is a critical need (practical needs and reputation) to ensure that the manual is as accurate and useful as possible. NOC proposes to coordinate this action by reviewing and cross-checking documentation with v3.6 stable code, editing where necessary and collaborating with code authors on updating sections found wanting.
