Extended Core Components
- 18 June 2024
Our extendend core components cover models for a comprehensive mapping of the Earth System and its interactions (e.g., atmospheric chemistry, ocean biogeochemistry, land ice, socioeconomics). While not required by the majority of users, these components offer flexibility for specific research questions. Our current extended core components include a tool that adds the capability to simulate aerosols and reactive trace gases to our core components (ICON-ART). It is the responsibility of natESM to seamlessly integrate these extended core components into the natESM system.
YAC - Yet Another Coupler
- 23 May 2024
Couplers allow the data exchange – e.g. of energy, momentum, water and important trace gases such as carbon dioxide – between the Earth system model components for ocean, atmosphere and land, and are essential for representing the climate system’s complex processes and feedbacks in the models.
ComIn - Community Interface
- 23 May 2024
The Community Interface (ComIn) organizes the data exchange and simulation events between the ICON model and “3rd party modules”. The concept can be logically divided into an Adapter Library and a Callback Register.
Welcome to the natESM system
- 12 July 2023
The aim of natESM is to develop a comprehensive Earth system modeling framework that operates seamlessly across multiple scales. It is built upon national model components and is intended for use in various domains, including research, operational applications, training, and education. The modeling system leverages German expertise while remaining open to international contributions, with an emphasis on minimizing dependencies. See more in our White Paper
This undertaking is intricate and multifaceted, necessitating the representation of a wide array of processes, interactions, temporal and spatial scales, and both existing and missing model components and parameterizations. This encompasses tasks such as simulation, data assimilation, and diagnostic workflows. The only way to address these demands effectively is through a dynamic model system, which can provide a comprehensive overview of the complexities inherent in this modeling system.
Core Components

The core components of the future natESM system will comprise models for atmosphere, ocean, and land.
Atmosphere

ICON-A: Roland Potthast
For the representation of the atmosphere, ICON includes a non-hydrostatic dynamical core operating on a icosahedral-triangular Arakawa C grid. Physics parameterizations for radiation, cloud microphysics (1- or 2-moment) and turbulence are always used, while orographic drag, subgrid cloud cover, and deep and shallow convection are parameterized or not depending on the configuration.
Infrastructure
- 27 June 2023
Tools and software libraries are regarded as infrastructure components in natESM, which are distributed independently but only show their full benefit in combination with climate models or climate data. These include, for example, libraries for improved MPI communication on HPC systems, I/O libraries, coupler, analysis tools or orchestration approaches for model runs.
