GENIE:GENIE Tuning rel-2-7 phase 2

=Strategy for tunings of release 2.7.n - Phase 2=

Summary
With the ENTS model component is selected, the model-data RMS difference computation for the relative humidity field requires revision 5915, which is not included in the tagged release version, in order to work correctly. Therefore, phase 2 tuning is based on a new tagged release version of the model, through the use of a branch  which will branch off from the tagged release version.

Model setup and compilation
Analogous to the setup and compilation of the base version of  described for the phase 1 of the tuning exercises, except that the source code is exported from   instead of from.

Modifications, corrections, and updates made in branch 'rel-2-7-4-tuning'
None, so far.

Base configuration
The phase 2 tuning exercises of the model are applied to the 36x36x16 equal-area-grid resolution of the model as set up for experiment  of the first phase of the tuning exercise (see the page for the phase 1 of the tuning exercises for further details]] with the land model component ENTS additionally enabled, and, except in one sensitivity experiment, the use of a depth- and stratification-dependent scheme parameterisation of the diapycnal diffusivity coefficient. The configuration files for 5000 year spin-up simulations for phase 2  are provided in the directory   (nm stands for the respective tuning setup).

Base parameters
Except for the parameters listed below, the base parameters are set to the same values as used for the base version of  used in phase 1 of the tuning exercises.

Tuning configuration
The parameter estimation problem is finding values for the parameters. Values and parameters typeset in bold are different from the corresponding values used for the tuning of the base version of  in phase 1 of the tuning exercises. For some parameters of the ocean model component, the width of the ranges has been narrowed (subjectively, guided by results of tuning exercise 1a), and the upper boundary of the scaling factor for the Atlantic-Pacific freshwater adjustment flux has been increased.

Build macro definitions
All settings are the same as used for the base version of  used in phase 1 of the tuning exercises.

Wind-related boundary conditions
All settings for the wind-related boundary conditions are the same as used for the base version of  used in phase 1 of the tuning exercises.

Target data
All settings related to the target datasets are the same as used for the base version of  used in phase 1 of the tuning exercises.

List of required input files
Names typeset in bold replace corresponding files used for the tuning of the base version of eb_go_gs in phase 1 of these tuning exercises. Names in italics denote input files which do not correspond to any of the input files required during the first phase 1 of these tuning exercises.

Validation
TODO: To be described and performed.
