| 73 | | * New TOP component structure with 5 modules handled with namelist parameter rather than CPP keys ( PISCES, CFC11/CFC12/SF6 carbon tracers, MY_TRC a template for new module, AGE a water age tracking and C14 a radiocarbon passive tracer ) |
| 74 | | * A new configuration was created to use the inert carbon tracers (CFCs) as a benchmark of new developments, named ORCA2_OFF_TRC |
| 75 | | * A common framework for TOP boundary conditions ( surface, coastal and open boundaries ) |
| 76 | | * PISCES has undergone several modifications and enhancements: |
| 77 | | * A new lability scheme for POC that can be activated from the namelist |
| 78 | | * An improved optional description of ligands for the iron cycle |
| 79 | | * Carbonate chemistry is based on MOCSY 2.0 |
| 80 | | * Kriest POC description has been removed |
| 81 | | * a quota version of the code can be activated (PISCES-QUOTA) |
| | 73 | * The passive tracers transport component was redesigned toward a modular structure and users can enable each module directly through logical flags in namelist_top (no more fortran macros!). |
| | 74 | * TOP currently accounts for the following 5 modules: CFC contains inorganic carbon tracers (CFC11/CFC12/SF6), MY_TRC is a template for new modules (or external couplings), AGE deals with water age tracking, C14 as a radiocarbon passive tracer, and the companion ecosystem model PISCES. |
| | 75 | * A generalized infrastructure was developed to handle the prescription of either surface, coastal, or open boundaries conditions for each passive tracer. |
| | 76 | * A new configuration, named ORCA2_OFF_TRC, was created to provide a benchmark simulation environment to deal with inert carbon tracers dynamics by exploiting the offline coupling with NEMO. |
| | 77 | * PISCES model contains new developments and modifications: |
| | 78 | * Particulate Organic Carbon (POC) component comes with a new lability scheme, while the former Kriest parameterisation was superseded; |
| | 79 | * A complex iron chemistry scheme is now available, with an improved description of ligands for the marine iron cycle |
| | 80 | * Carbonate chemistry is based on MOCSY 2.0 routines (see Orr and Epitalon, 2015), by complying also with CMIP6 standards. |
| | 81 | * Ecosystem components can be optionally modelled by means of explicit nutrient quotas (PISCES-QUOTA) |
