The Coupled Model Intercomparison Project (CMIP) is one of the biggest international efforts aimed at better understanding the past, present, and future of climate changes in a multi-model context. A total of 21 model intercomparison projects (MIPs) were endorsed in its sixth phase (CMIP6), which included 190 different experiments that were used to...

The MPI-ESM1.2 is the latest version of the Max Planck Institute Earth System Model and is the baseline for the Coupled Model Intercomparison Project Phase 6 and current seasonal and decadal climate predictions. This paper evaluates a coupled higher-resolution version (MPI-ESM1.2-HR) in comparison with its lower-resolved version (MPI-ESM1.2-LR). We...

Weather and climate models are complex pieces of software which include many individual components, each of which is evolving under pressure to exploit advances in computing to enhance some combination of a range of possible improvements (higher spatio-temporal resolution, increased fidelity in terms of resolved processes, more quantification of un...

Where will the development go? Whereas some skepticism still seems to be appropriate as to how far the initiatives and projects described above will have a lasting influence on the every-day-life of the single researcher, it seems to be out of question that even more and harder, joint efforts of the community are necessary to cope with the big data...

In this last book in a series of briefs on “Earth System Modelling” we are concerned with the treatment of data and metadata that are produced during the complete workflow of Earth system modeling.

The Community Climate System Model (CCSM) development and coordination is based at the National Center for Atmospheric Research (NCAR) in Boulder, Colorado, USA. CCSM is a state-of-the-art global climate model consisting of four fundamental physical components: an atmosphere model, an ocean model, a land surface model, and a sea ice model. In addit...

Collected articles in this series are dedicated to the development and use of software for earth system modelling and aims at bridging the gap between IT solutions and climate science. The particular topic covered in this volume addresses the Grid software which has become an important enabling technology for several national climate community Grid...

Collected articles in this series are dedicated to the development and use of software for earth system modelling and aims at bridging the gap between IT solutions and climate science. The particular topic covered in this volume addresses the issue of data input/ouitput and post-processing in the context of Earth system modeling, with an emphasis o...

This article consists of a collection of slides from the author's conference presentation.

Climate change is likely to be one of the defining global issues of the 21st century. The past decade—the hottest in recorded history—has witnessed countries around the world struggling to deal with drought, heat waves, and extreme weather. The sheer scale of the problem also makes it hard to understand, predict, and solve. Climate science journals...

Climate Knowledge Discovery Workshop; Hamburg, Germany, 30 March to 1 April 2011 Do complex networks combined with semantic Web technologies offer the next generation of solutions in climate science? To address this question, a first Climate Knowledge Discovery (CKD) Workshop, hosted by the German Climate Computing Center (Deutsches Klimarechenzent...

The Model Coupling Toolkit (MCT) MCT provides datatypes and methods for creating parallel couplers and parallel coupled models out of one or more models of physical systems. MCT handles common coupling tasks in a distributed memory parallel application.

The Earth System Modeling Framework or ESMF is open source software for building modeling components and coupling them together to form weather prediction, climate, coastal, and other applications. ESMF was motivated by the desire to exchange modeling components amongst centers and to reduce costs and effort by sharing codes.

Earth System modeling is indispensable for our understanding of current and future climate change. Here we will address one of its components, the ocean, capable of storing large amount of heat and thus influencing the climate on large time and space scales. Currently, numerical modeling of ocean general circulation is dominated by models formulate...

The increasing complexity of Earth system models and the computing facilities needed to run those models put a heavy technical burden on research teams active in climate modeling. To ease this burden, a European collaborative venture called PRISM was initiated in December 2001 to organize a network of experts in order to share the development, main...

Approximately 40 European institutions agreed to work together and cooperate towards the development of a European network for Earth system modelling. They currently develop different activities to reach the following aims: - Increase scientific knowledge about the Earth System by pursuing ambitious studies on the feedback cycles within the Earth S...

A primitive equation model of an idealized ocean basin, driven by simple, steady wind and buoyancy forcing at the surface, is used to study the dynamics of mesoscale eddies. Model statistics of a six-year integration using a fine grid (1/6 degrees X 0.2 degrees), with reduced coefficients of horizontal friction, are compared to those using a coarse...

Uses a high resolution model of the wind driven and thermohaline circulation in the North and equatorial Atlantic Ocean to study the structure and variability of the boundary current system at 26 degrees north. The model is the first Community Modelling Effort of the World Ocean Circulation Experiment. A series of model runs examined model sensitiv...

Earth System science in general is based upon modelling and observations. The bulk of the raw data model output and Earth observation data is stored in a few centres, distributed over Europe and worldwide. The scientists in principle rely on the avail-ability of easy and transparent access to these data-bases, which is not given today for different...
