INGV.1 — Atmospheric Pressure for Filtered free surface

Motivation: Better representation of sea surface height spatial and temporal variability by consideration of surface pressure in limited area model domain in case of filtered free surface formulation
Status: Atmospheric Pressure term has been introduced in case of filtered free surface by the INGV group in the operational model of the Mediterranean Sea. For limited area model this requires an appropiate treatment of mass fluxes at the lateral open boundaries
Main tasks: recode according consortium rules; ensure compatibility between filtered free-surface / volume conservation and new mass fluxes through lateral open boundaries

INGV.2 — Implementation of new bulk formula

Motivation: Air-sea interaction drives most of the ocean processes at short-medium and long time scales. Thus an appropiate representation of momentum and buoyancy fluxes is mandatory foe modelling studies. At the present two different packages of bulk formulae are provided with the NEMO code and the users can choice according specific needs. A further option will be introduced on the basis of INGV modelling experience in the Mediterranean Sea.
Status: The bulk formulae are in use in the Mediterranean Forecasting System operational version of NEMO code.
Main tasks: Re-write the code according to consortium rules - Modify CPP key option and namelist options accordingly.

INGV.3 — Implementation of wave forcing interface

Motivation: Ocean waves play a cricual role in surface and near surface dynamics, thus a simple interface allowing NEMO to read wave-model output is needed. Wind stress is known to be affected by wind waves surface roughness and for that reason NEMO will be developed to read an external neutral drag coefficient from a wave model. Moreover 2 parameterizations for the turbulent part of the drag coefficient will be developed in the NEMO code.
Status: implementation of wind stress with turbulent wave components from an external wave model in the NEMO. Version for the Mediterranean Sea.
Main tasks :
(1) Insertion of a compilation key in order to introduce a generic interface to read wave model output.
(2) Insertion of the compilation key (or namelist parameter) in order to activate the usage of a standard drag coefficient (probably default) or the usage of a neutral drag coefficient coming from a wave model.
(3) Insertion of the two compilation keys (or namelist parameters) in order to activate two different parameterizations of the turbulent component of the external drag coefficient.
(4) Perform tests.

INGV.4 — Update of Richardson ldzdf routine for PP new scheme

Motivation: Modify the existing Pacanoski & Philander (PP) scheme to introduce mixed layer dynamics in order to have a robust and easily adaptable vertical mixing scheme for operational purposes
Status: Preliminary tests already carried out; needs to be written accordingly consortium rules and ensure proper propagation of variables between air-sea interface routines and vertical mixing scheme
Main tasks: Modify the existing module - introduce needed variables in the namelist - perform tests
