Nested simulation with carbon dioxide removal

This tutorial describes a ROMS set-up for conducting a carbon dioxide removal (CDR) intervention simulation via ocean alkalinity enhancement (OAE). It consists of three ROMS simulations:

1. a lower-resolution “parent” simulation of the northeast Atlantic, which generates initial and boundary conditions for…

2. a higher-resolution “child” simulation of the northwest coast of Iceland, where an alkalinity perbuation is made and eventually fluxes out into…

3. a second run of the parent simulation, which tracks CDR-relevant tracers that have left the child domain in (2).

• 1. Parent simulation
• 2. Child simulation with CDR
• 3. Parent simulation re-run with upscaled CDR
