What is GMD?

• What is GMD?
• Why do we need it?
• Who is involved?
• How will it work?

• 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

• 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.

  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.)

• 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

• 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.

• Responsibility for model development and
  bug-fixes..

We found a bug in the model
radiation code, which manifests itself at high
CO2. When we approached the ,
, they were not interested.

• 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

• 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!
