Hi Patrick,

Good timing! I knew there were some Azimuth coding challenges or open code project ideas somewhere in the Azimuth ecosystem but I never thought to look in the googlecode repo, so thanks.

Some coding things going on at the moment include:

[[Allan Erskine]] set up a [repo on github](https://github.com/azimuthproject). Git is what he and I use but we haven't yet due to other pressures.

[[Tim van Beek]],[[Allan Erskine]] and [[Glyn Adge]] designed and wrote an interactive [stochastic bistable model](http://www.adgie.force9.co.uk) in javascript which I think's really cool.

[[Nathan Urban]] came up with what I think is a list of possible climate-related model projects in [this thread](http://forum.azimuthproject.org/discussion/1116/american-geophysical-union-talk-december-6th/#Item_30); I think it's worth reposting here:

"Some possibilities:

* An 1D upwelling-diffusion energy balance model (generalization of the simple 0-dimensional linearized dynamics we’ve looked at earlier). This illustrates some transient dynamics of ocean heat uptake and can be tuned to the historical climate to make simple predictions.
* A 1D radiative-convective model of the atmosphere. (I’ve always wanted to code up some variant of some of Jim Kasting’s models to look at runaway and moist greenhouses.)
* More sophisticated glacial-interglacial dynamical models (Saltzmann style) or Snowball Earth energy balance models for paleoclimate.
* Some simple fluid dynamics on a rotating planet, e.g. a beta-plane (tangent plane) approximation, or something illustrating a baroclinic instability in the atmosphere or a ocean double-gyre configuration, eventually working up to a simple aquaplanet. This relates to the “ocean modeling” thread. I don’t know if you could make the resolution coarse enough to be interactive, yet fine enough to be realistic.
* A box model of the terrestrial or ocean carbon cycle (with ocean biogeochemistry like Revelle factors), or an ecological model (photosynthesis / respiration of vegetation, or NPZD model of plankton).
* A simple 1D flowline model of a glacier or ice sheet."

Have a happy holiday
