NEMO Version 5.0 Biogeochemistry Demonstrator

This test case provides a demonstration of PISCES, the biogeochemical (BGC) model included within NEMO V5.0, over the full global ocean. Provided with this test case are scripts for determining the dominant phytoplankton and zooplankton at each grid point in the global ocean for two reference runs, one based on the PISCES (P4Z) configuration and one based on the PISCES QUOTA (P5Z) configuration.

This demonstrator helps to educate new users of NEMO interested in running with BGC on the changes necessary to run the different configurations of PISCES. Comparison of the outputs from each run also allows to explore the effect of having a higher complexity model (through the additional phytoplankton included within PISCES QUOTA) and the impact this has on the dominance of each plankton type.
