JCM: Acknowledgements

  • (See also development history) So many people have helped during development of JCM. Particular thanks are due to:

  • Jesper Gunderman (DEA) and Peter Laut (DTU), who provided the vital "break" inviting me to work with them in Copenhagen, and explaining their methods for solving the models.
  • Brian Lucas, Lawrence Hislop, Aake Bjorke, and many others in Arendal, for a great experience working with UNEP-GRID.
  • Fortunat Joos (KUP), and many others here in Bern, for sharing much insight into climate models, also Jose Romero (BUWAL) for enthusiastic support of this project.
  • Jean-Pascal van Ypersele (UCL), for support and encouragement for the longer-term development of this work.

    I should also thank colleagues in GCI for introducing me to climate policy, to friends in Edinburgh who helped me during spring 2001, and to many others who gave ideas and encouragement regarding the model. And not least, I thank friends in many places, who helped this "nomad with a laptop" to feel at home and to escape the computer occasionally to enjoy the real world!

    Original Models and Data

    As JCM aims to reproduce IPCC predictions, it incorporates formulae from many research groups. Although "simple" carbon/climate models can be described with relatively few boxes/equations, the validity of such "conceptual" models depends on the careful tuning of the parameters, to capture the response of more complex GCMs, or to match historical measurements. This is not an easy task, and these models have taken years to develop.

    So, the effort that has gone into the original models, should also be acknowledged, particularly the Bern model used for the carbon-cycle / chemistry in JCM, and the Wigley-Raper model used for the temperature / sea-level.

    Many sources of data are also acknowledged, particularly from RIVM's Image model used for the socioeconomic data, from CDIAC for national emissions data, and from IPCC-DDC for regional climates.
