What is GMD?

• What is GMD?

• Who is involved?
• How does it work?

2

• Geoscientific Model Development (GMD) is an
  international scientific journal dedicated to the
  publication and public discussion of the
  description, development and evaluation of
  numerical models of the Earth System and its
  components. Manuscript types considered for
  peer-reviewed publication are
• Model descriptions
• Development and Technical papers
• Benchmarking papers
• Model intercomparison descriptions

3

• Geoscientific model descriptions, from box
  models to GCMs
• Development and Technical papers, describing
  development such as new parameterisations or
  technical aspects of running models such as the
  reproducibility of results
• Papers describing new standard experiments for
  assessing model performance, or novel ways of
  comparing model results with observational data
• Model intercomparison descriptions, including
  experimental details and project protocols.

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.

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

It turns out that the have lost the input
files and code used to create the boundary
conditions for their standard control
simulation.

• MIP descriptions too detailed

.the paper contained some description of the
experimental design and also some results. .one
of the reviewers thought more science was
required to make it publishable, and suggested
cutting various bits out. .once the protocol
description and discussion was given its freedom
it actually became rather interesting, as well as
being an awful lot easier to follow.

• Detailed model description papers.
• May include a user manual and actual code (as
  supplementary information).
• 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.
