NEMO relocatable regional ocean modelling
As part of the ACCORD project we have been developing tools to accelerate the development and deployment of regional ocean models.
The primary advantages of bespoke configuration are:
- The resolution of the region of interest can be finer than with freely available (typically global or macro-regional) datasets.
- The experiments can be customised in terms of variables carried and/or frequency of output.
- Regional models can computationally cheap to run and make their translation to partner nations easier.
Rapid deployment has two parts: Part 1: Configuration and Part 2: Validation.
As part of ACCORD we are building a 3D physical (NEMO) plus ecosystem (ERSEM) model of South East Asia. This configuration spans 75E to 135E and -20N to +25N. The model grid has 1/12 degree (approx. 9km) lat-lon resolution and 75 vertical levels, which follow the terrain in shallow waters.
As a result of the ACCORD rapidly deployable workflow, a number of other projects have been supported and configurations have been built (including but not limited to):
A locally hosted surge model of Madagascar Met Service: (C-RISC)
A 3D regional model of the Caribbean (CME; github)
A 3D regional model of East Africa (Solstice)
This activity has been recognised as transformative and is now supported under CLASS.
