EarthN: A New Earth System Nitrogen Model [PDF]

Geochemistry, Geophysics, Geosystems, 2018
The amount of nitrogen in the atmosphere, oceans, crust, and mantle have important ramifications for Earth's biologic and geologic history. Despite this importance, the history and cycling of nitrogen in the Earth system is poorly constrained over time ...

Confronting Earth System Model trends with observations. [PDF]

Sci Adv
Anthropogenically forced climate change signals are emerging from the noise of internal variability in observations, and the impacts on society are growing. For decades, Climate or Earth System Models have been predicting how these climate change signals will unfold.

The ICON Earth System Model Version 1.0

Journal of Advances in Modeling Earth Systems, 2022
This work documents the ICON‐Earth System Model (ICON‐ESM V1.0), the first coupled model based on the ICON (ICOsahedral Non‐hydrostatic) framework with its unstructured, icosahedral grid concept. The ICON‐A atmosphere uses a nonhydrostatic dynamical core

U.K. Community Earth System Modeling for CMIP6 [PDF]

Journal of Advances in Modeling Earth Systems, 2020
AbstractWe describe the approach taken to develop the United Kingdom's first community Earth system model, UKESM1. This is a joint effort involving the Met Office and the Natural Environment Research Council (NERC), representing the U.K. academic community. We document our model development procedure and the subsequent U.K.

Differentiable programming for Earth system modeling

Geoscientific Model Development, 2022
Abstract. Earth system models (ESMs) are the primary tools for investigating future Earth system states at timescales from decades to centuries, especially in response to anthropogenic greenhouse gas release. State-of-the-art ESMs can reproduce the observational global mean temperature anomalies of the last 150 years.
