The Azimuth Code Project is an online open source project that will provide source code for the analysis and simulation software used at the Azimuth project. It is hosted by google and available under the LGPL (lesser gnu public license).
We will try to provide well documented, simple and up-to-date implementation, mainly for instructional purposes. As a side effect we will try to show that clean, simple, open-source, well-managed and up-to-date code handling is possible at a low cost, and how it can be done. The creation, documentation and publication of custom extensions to packaged software is supported, too.

The code is hosted here (SVN repository):
A second google project is based on a Git repository:
This model was explained in the blog post Increasing the signal-to-noise ratio with more noise.
Allan Erskine has also created some models of bistability. The first was for a static climate system:
The second was for a dynamical system:
Michael Knap combined the latter model with the work on stochastic resonance to get a stochastic resonance model more explicitly connected to climate physics, which is here:
Taylor Baldwin simplified Michael Knap’s model to make one that will be better suited to a general audience once we add a good simple explanation:
Many papers in climate science present results that cannot be reproduced. The authors present a pretty diagram, but don’t explain which software they used to make it, and don’t make this software available, don’t really explain how they did what they did. This is a problem, because scientific results need to be reproducible. Any software that is used deserves to be versioned and published alongside any scientific results.
All of this is true for large climate models such as General Circulation Models as well—but the problem becomes much more serious, because these models have long outgrown the extent where a single developer was able to understand all the code. This is a kind of phase transition in software development: it necessitates a different toolset and a different approach to software development.
Show how computer code can easily be versioned and published along with any scientific results that are based on the code, by example.
All code used in science should be open source, everyone should be allowed to use it.
Show how code can be documented
Show how code can be structured using established paradigms from software engineering, by example,
in order to make it as easy as possible for others to understand it.
