The Arctic has become the focus of many new investigations and studies across a number of disciplines. In many cases, this research is integrating diverse new data sets, observations, and modeling, and making connections among and across the biosphere, oceans, atmospheres, space, and geophysical environments. These papers include historical and new research on the Arctic and represent the following AGU journals: Earth’s Future, Earth and Space Science, Geochemistry Geophysics Geosystems (G-Cubed), Geophysical Research Letters, Global Biogeochemical Cycles, JAMES (Journal of Advances in Modeling Earth Systems), JGR: Oceans, JGR: Atmospheres, JGR: Solid Earth, JGR: Space Physics, JGR: Biogeosciences, JGR: Earth’s Surface, Reviews of Geophysics, Space Weather, and Water Resources Research.

The Max Planck Institute for Meteorology Earth System Model version 1.2

Last updated:

The Max Planck Institute for Meteorology has a thirty year history of developing state-of-the-art climate models and MPI-ESM1.2 is the latest iteration. The model includes improvements to the carbon-cycle, an innovative aerosol climatology and the atmospheric physics, and for the first time, we elaborate on an explicit strategy to tune the models climate sensitivity to improve the match to observed warming. The relatively low computational cost of the model has allowed us to perform a 100-member ensemble of the historical experiment, permitting us to compare the model to observations in innovative ways and sparking new research previously not possible.

The Max Planck Institute for Meteorology Earth System Model

B. Stevens
This special section is devoted to the scientific description of the MPI-ESM, the Earth System Model developed by the Max Planck Institute for Meteorology. The MPI has a long history of developing high-quality coupled models. This newest generation of our coupled model is the first to systematically incorporate the carbon cycle and represent dynamic vegetation, but equally important is its improved representation of basic physical processes. The papers in this section present a description of the MPI-ESM, and an initial evaluation---including the development of several novel configurations and features.
