Development of the New Zealand Earth System Model: NZESM

Weather and Climate (2016)

The New Zealand Earth System Model (NZESM) is currently under development to help inform stakeholders in New Zealand about climate change.

The development of the NZESM represents a step-change in model complexity for New Zealand science, and a major motivation for its development is to reduce Southern Hemisphere specific modelling problems such as the formation of Southern Ocean sea ice and Antarctic Bottom Water.

Over the next 5 years, the NZESM will be run to produce hindcasts for the past 150 years and projections for up to 200 years into the future.
