1. Geoscientific Model Development An Interactive Open Access Journal of the European Geosciences Union  What is GMD?  Why do we need it?  Who is involved?  How will it work?

2. Geoscientific Model Development An Interactive Open Access Journal of the European Geosciences Union Geoscientific Model Development (GMD) is an international scientific journal dedicated to the publication and public discussion of the description, development and benchmarking of numerical models of the Earth System and its components. Manuscript types considered for peer-reviewed publication are: Model descriptions Model intercomparison descriptions Benchmarking papers Development and Technical papers

3. Geoscientific Model Development An Interactive Open Access Journal of the European Geosciences Union A few ‘Case Studies’ of bad practice……. (the names have been changed to protect the innocent!)  Papers containing ‘too much’ model description cut down or even rejected…. “There is 14 pages of models description, and only 6 pages of experiments, results and discussion. It appears to me that needs more scientific analysis for publishing”.

4. Geoscientific Model Development An Interactive Open Access Journal of the European Geosciences Union A few ‘Case Studies’ of bad practice……. (the names have been changed to protect the innocent!)  Institute webpages with links to model code…. “Bottomline: you should use the new version and forget the old one - if you ask us. (The plots on the web site are old - it is about time we supplied some numerical data for such checks as you are doing.)”

5. Geoscientific Model Development An Interactive Open Access Journal of the European Geosciences Union A few ‘Case Studies’ of bad practice……. (the names have been changed to protect the innocent!)  Tracibility of model versions….. “there is no need to worry, when you get more barren than with the Journal 1 version. The version, which is on the web, produces more barren, because the water balance has been improved (Journal 2), which leads to drier conditions ….. You can look at the latest publication from in Journal 3”

(the names have been changed to protect the innocent!)  Loss of institution ‘memory’….. “It turns out that the Centre have lost the input files and code used to create the boundary conditions for their standard control simulation.”

7. Geoscientific Model Development An Interactive Open Access Journal of the European Geosciences Union A few ‘Case Studies’ of bad practice……. (the names have been changed to protect the innocent!)  Responsibility for model development and bug-fixes.. “We found a bug in the model radiation code, which manifests itself at high CO 2. When we approached the,, they were not interested.”

10. Geoscientific Model Development An Interactive Open Access Journal of the European Geosciences Union “Missing” subject areas:  Planetary and Solar System Sciences  Solar-terrestrial Science  Solid Earth (Geochemistry, Mineralogy, Petrology, Volcanology, Magnetism, Palaeomagnetism, Rock Physics, Geomaterials)

11. Geoscientific Model Development An Interactive Open Access Journal of the European Geosciences Union  Detailed model description papers.  May include a user manual and actual code.  Submission of short papers describing subsequent model development and bug-fixes will be encouraged. These papers will be electronically linked to the orginal, allowing a ‘portfolio’ to be developed.  All papers to include model name and version number in title. = Traceability and Reproducibility

12. Geoscientific Model Development An Interactive Open Access Journal of the European Geosciences Union  GMD will provide a means by which the hard work of model developers can be formally recognised and published.  Special Issues for very large models, such as GCMs.  Standard EGU format, including Open Access, Open Reviews, Discussions paper.  First 1000 pages are free!
