Full Changelog: AWI-CM3_v3.2...2.5.0.1_de

AWI-CM3_v3.2

Version of FESOM2 that was used for AWI-CM3.2

Includes all changes from FESOM 2.1, FESOM 2.1.1 and FESOM 2.5.

In addition using this release FESOM2 is capable of writing grid corner points for OASIS, provided the mesh has no bad coastal nodes. #432 #450

FESOM2.5

Main changes

• Complete refactoring of the code in order to implement modular structure. Now variables are wrapped in derived types. For tracers [#167, #185 ], dynamics [ #214, #219, #228, ], ice [#251, ]

• Add OpenMP support [#196, #217 , #220, #222, #226, #227, #232, #233, #235, #236, #241, #242, #244, #246, #247, #256, #269, #293, #346, #406], with binary reproducibility #357

• Implementation of binary restarts and parallel reading of restarts #260, #265, #296

• Add capability to easilly extract dwarfs (computational kernels) from the code, so that they can be optimised separatelly (#297, #302, #303, #304, #367)

• Energy diagnostic #416, #417

Improvements for coupling with atmospheric models

• Multiple fixes for AWI-CM3 #352, #374
• FESOM main split in three parts (as required for IFS coupling) #195
• Add a switch to build FESOM as library (for IFS coupling) #207 #229, #231
• Implement IFS interface #224, #238, #239, #327
• IFS coupling related changes #321, #324, #331, #332, #429, #433
• Send ocean variables to IFS to output them on atmospheric grid #435
• Big IFS related update #388, that includes:
  • coupling of surface ocean currents (took nodal velocities instead of velocities on elements)
  • optimization of coupling interface (packing of fields, p2p instead of alltoallv) following what was done for NEMO4
  • extra diagnostics are available on IFS grid (MLD, ave T 300m, ave S 300m, 20C isotherm, etc) and thus in GRIB output
  • reduced standard I/O output in single-executable runs

Compiler and HPC support

• nvfortran compiler support #266, #290, #291, #317, #328, #329, #376
• Use consistent target attribute (for Cray compiler) #198

New features

• Automatic rotation for vector fields, no need or rotation in postprocessing #301, #335
• Allow topography to be read on elements and nodes #359
• Support for driving FESOM with the windstress (instead of the wind speed -> bulk formulas) from reanalysis #366
• Add MLD3 with cmor compliant density threshold of 0.03 kg/m³ #383
• Chlorophyll climatology can be used instead of constant value. Shall be activated through namelist #339

• Additional IO output for upper levels for nextGEMS #436

Improvements for High resolution simulations

• Brunt-Vaisala frequency is smoothed spatially before it is given to the mixing schemes. This damps some mode which is expressed as a grid noise in the modelled fields (mainly at the equator) #287
• Smoothing Bv in vertical is necessary in order to avoid vertival noise in Kv/Av #385
• Fix bug, when visc_gamma0, visc_gamma1 & visc_gamma2 were used instead gamma0_tra, gamma1_tra & gamma2_tra in diff_part_bh #276
• Multiple bugs fixed in biharmonic tracer diffusion, that allow better results for high resolution simulations #277, #282
• Bug fix in pressure_bv (depth computatiopn for pressure contribution) #320

Bug fixes

• Multiple TKE+IDEMIX fixes #351
• fix bug with reading runoff and SSS #177
• Remove last occurence of execute_command_line function, was failing too often #318

Documentation

• Includes the formerly separate documentation repository directly along with the source code #344

Beginning of major refactoring

• Refactoring of the code to get rid of global memory modules. A derived type for the mesh structure has been created and all the routines modified such that they receive the mesh as an argument. let us see whether this strategy will work. If so all other modules shall be processed in a similar manner.
• Add discrete variance decay (DVD) computation of Klingbeil et al., 2014.
• Kick out unused namelist flags from namelist.config.
• Include new scheme + parameters for the vertical tunning of Gent McWilliams.
