Abstract

This action will enhance the tidal harmonic-analysis diagnostics available in the NEMO framework: the replacement of the current implementation by a facility for generic multiple linear regression will enable tidal harmonic analyses of three-dimensional fields, make harmonic analyses across model restarts possible, and improve the computational efficiency of the analysis, as well as facilitate a wide range of non-tidal regression analyses.

Description

The harmonic-analysis diagnostics available in the current reference code is limited to two-dimensional fields (surface only), is activated via a preprocessor key, uses unconventional namelist parameter names, uses a mixture of dynamic and static allocation for large arrays, and appears to be computationally inefficient. Further, while being based on multiple linear regression, the current implementation does not provide for regressions on harmonic components other than tidal constituents.

This action will replace the current tidal harmonic-analysis diagnostics with a generic implementation for multiple linear regression analysis that can be utilised for both tidal harmonic and non-tidal regression analyses. This implementation will provide harmonic-analysis diagnostics enhancements previously tested in a pre-4.0beta NEMO version by N. Bruneau: the analysis of three-dimensional fields, analysis across model restarts, and improved computational efficiency.

In contrast to both the existing harmonic analysis diagnostics in the reference NEMO code and the enhanced pre-4.0beta version by N. Bruneau, the new implementation will make extensive use of XIOS and an off-line tool. This approach should make it possible to simplify the regression analysis-related Fortran module in the core NEMO code, to relocate the regression-analysis configuration to XIOS configuration files, and to enable the selection of any model field handled by XIOS for analysis.

Detachment of the context-definition closure from subroutine iom_init of module iom to enable additional context definition outside subroutine iom_init (ticket #2175).

The closure of the context definition is now available in the new public subroutine iom_init_closedef of module iom. By default, this subroutine is called by subroutine iom_init, so that the default behaviour of iom_init remains unchanged. Optionally, subroutine iom_init can now be made to keep the context definition open by setting the optional argument ld_closedef to .FALSE.; this enables continued definition of the context until subroutine iom_init_closedef is explicitly called.
