#2129 AGRIF-02_CMEMS_improve_global rblod Unspecified failed no
#2111 CMCC-01_sciliberti_BDYModel sciliberti Action is still under development - in particular, devs on 4.0 need to be setup, actually partially implemented for 3.6. failed no
#2193 CMCC-03_Clementi_Add Wave Diag emanuelaclementi In progress. Part of this action was included in in previous WP2018 actions (VALID-08_Drudi_Wave_ORCA2, VALID-09_Lovato_TestWave_MedSea) To be finalized by end 2019. failed no
#2052 ENHANCE-01(2018WP)_Romain-massfluxconvection rbourdal first implementation ok; C1D case under evaluation; 3D case to be done pending no
#2142 ENHANCE-02_Pierre Mathiot_ISF mathiot Status 08/2019: Work started on 2 branches: one for domcfg (inclusion of the new geometry computation) and one on NEMO itself (cleaning, new method to couple with an ice sheet model, ... see wiki for details). Testing: - test on ISOMIP successful. Still to do: - add the WED025 configuration (bdy, sea ice, ice shelf, tides) configuration. - add an updated ISOMIP test (static geometry and moving geometry). - test it with our prototype GO8 on eORCA025. - review. Will be ready for the merge. failed no
#2143 ENHANCE-03_PierreMathiot_DomcfgTools mathiot - Change in domcfg to define the closed sea and its river mouth using a lat/lon seed is done. - Change in NEMO to manage multiple closed sea with the same river mouth. - tested in a very idealised case. Still to do: - test it with eORCA025, eORCA1, ORCA2 (to see if the same namelist block works for various configuration with different lakes activated). Will be ready for the merge party. failed no
#2167 ENHANCE-04_AndrewC-reporting acc Most of the basic functionality has been implemented post-merge (2018) and is already in both the trunk and release. See: wiki:2019WP/ENHANCE-04_AndrewC-reporting for details. There is more that can be done to improve and enhance options and the task is likely to be revisited before the next merge (2019). The key further development planned is to implement single-core read and broadcast for common, small-volume inputs (e.g: EMPave.dat, namelists etc.). failed no
#2175 ENHANCE-05_SimonM-Harmonic_Analysis smueller Implementation in progress pending no
#2176 ENHANCE-07_JamesH-sigma_under_ISF jamesharle Unspecified failed no
#2045 ENHANCE-08(2018WP)_Gurvan-Implicit_Drags gm Require the RK3 environment. Two steps: (1) proper implicit top & bottom drag. (2) implicit ice-ocean drag. Step (1) expected for WP2009 Step (2) is unscheduled: it requires significant changes in the SI3 architecture failed no
#1959 ENHANCE-09_Jerome_freesurface(2017WP) jchanut Tasks 1) and 3) are already completed and available in NEMO 4.0, hence only task 2) (pressure gradient gradient correction) is remaining. Implementation plan is in progress. failed no
#2315 ENHANCE-11_CEthe_Shaconemo_diags cetlod Ongoing, planned for the merge 2019 failed no
#2194 ENHANCE-12_SimonM-Tides smueller Implementation in progress pending no
#2217 HPC-01_Mike Bell_OpenMP mikebell Unspecified failed no
#2011 HPC-04(2018WP)_Mocavero_mpi3 mocavero Some tests on a significative kernel have been executed (using a mini-app approach). The integration of the neighbourhood collective communications in the trunk is ongoing. The branch will be ready for merge party end 2019 failed no
#2166 HPC-06_SimonM-extendedhaloes smueller On hold failed no
#2195 HPC-08_XXX_fldread_with_XIOS andmirek I have implemented use of XIOS to read weights file and initial conditions. Next step is to use it to read forcing files. There are few issues related to the way XIOS handles reading which may make implementation difficult. First XIOS can't read data from files split in time (it writes data without any problems) and this is what happens in MetOffice configuration. In addition XIOS can't jump between time records - it can read only next time record. As a result replicating full functionality currently in NEMO will be difficult. Inability of XIOS to jump between records makes reading forcing difficult if there is time interpolation involved and forcing for different parts have different frequencies. failed no
#2198 HPC-10_Mike_Tiling mikebell Unspecified failed no
#2040 HPC-13_Mixed_precision_study-13.2_Implementation mcastril Implementation will start this year, now that the methodology is ready and it is technically possible to do the automatic analysis in a short time. pending no

Work has begun on a range of approaches to reduce the too-deep winter mixed layers. a. Reduction in the effectiveness of the Langmuir mixing in cases where the ratio of the Stokes penetration depth to the boundary layer depth is small. and b. Reduction in effectiveness of shear-turbulent, Langmuir and convective deepening when the respective eddy turnover timescales (hbl/u* etc.) approach the inertial timescale 1/f. failed no
