  • CKD Workshop

    Welcome to the Climate Knowledge Discovery community project page

    One of the largest repositories of scientific data in any discipline is the model-generated and observational geoscience data produced and used in climate science. The data volumes from climate modeling will continue to increase dramatically, and the interpretation of this data requires new approaches - we are entering the age of data-intensive science. Future climate data analysis requires a suite of new techniques interpreting and linking phenomena on and between different time- and length scales as well as realms and processes. Such tools could provide unique insights into challenging features of the Earth system, including extreme events, nonlinear dynamics and chaotic regimes....

  • ENES Benchmark Suite

    The ENES (European Network for Earth System modelling) Benchmark Suite is a collection of real application codes used for Earth System Modelling and prepared for benchmarking of HPC systems. According to the intention and complexity the provided benchmarks are divided into the following categories:...

    • CMCC-CESM-NEMO Benchmark

      CMCC–CESM–NEMO is the physical basis of the new CMCC (Centro Euro-Mediterraneo sui Cambiamenti Climatici) Earth System Model (CMCC-ESM). It is a global coupled climate model derived from the NCAR coupled model CESM, where the ocean component is NEMO rather than the NCAR ocean model. In CMCC-CESM-NEMO all the climate components (atmosphere, ocean, land and sea-ice) are fully coupled....

    • Coupler Benchmarks

      On the road to exascale, the performance of the coupling technologies is becoming a major challenge in weather and Earth System Models (ESMs). Different coupling technologies are used today to link ESM components (e.g. the atmosphere, oceans, land, sea ice, etc.) and although their implementations differ vastly, they typically carry out similar functions such as managing data transfer between two or more components, interpolating the coupling data between different grids, and coordinating the execution of the constituents....

    • EC-EARTH Benchmark

      The Earth System Model EC-EARTH is developed as part of a Europe-wide consortium. EC-Earth component models are IFS for the atmosphere, NEMO for the ocean, LIM for the sea-ice, and HTESSEL for the land surface coupled through the OASIS coupler....

    • ICON Benchmark

      The new generation unified weather forecasting and climate model ICON (ICOsahedral Non-hydrostatic model) is jointly developed by Max-Planck-Institut für Meteorologie and German National Meteorological Service, the Deutscher Wetterdienst (DWD). ICON employs triangular and hex-/pentagonal grids arising from iterative subdividing of the edges of the icosahedron (polyhedron with 20 triangular faces) mapped to the globe....

    • ICON Kernels

      ICON Kernels focus an selected functionality of the full ICON model with the objective to minimize the following criteria which are considered to hinder ICON software analysis and development:

      • Size of entangled source code
      • Build and experiment setup complexity, including software environment requirements...
      • ICON Communication Kernel

        The ICON communication kernel focuses on the following features of the full model:

        • Functionality to read ICON grid files.
        • Grid decomposition controlled by namelist variables.
        • Implements a library which should be usable by other ICON kernels with communication requirements....
    • IPSLCM Benchmark

      IPSLCM (IPSL Coupled Earth System Model) is a full earth system model. In addition to the physical atmosphere-land-ocean-sea ice model, it also includes a representation of the carbon cycle, the stratospheric chemistry and the tropospheric chemistry with aerosols. The benchmark includes sources, utilities and additional files required to run and check a short simulation. IPSL Coupled Earth System model benchmark is available for two different generations of IPSLCM: IPSLCM5 (2010-2015) and IPSLCM6 (2016-2019)....

    • MPI-ESM1 Benchmark

      MPI-ESM1 is a comprehensive global Earth System Model developed at the Max-Planck-Institut (MPI) für Meteorologie. MPI-ESM1 consists of component models ECHAM/JSBACH representing atmosphere, land surface, soil and vegetation and MPIOM/HAMOCC describing ocean, sea ice and ocean biogeochemistry. ECHAM/JSBACH and MPIOM/HAMMOC run as separate executables coupled by the OASIS3-MCT coupler. Following model setups are available:...
