What is GMD?

Why do we need it?

Who is involved?

How does it work?


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


• 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.


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….




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”.




Tracibility of model versions…..




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’…..




Loss of institution ‘memory’…..

“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.
