ASIS:Main

Ice flow solver
Discuss the numerical implementation of: * Thickness solver * Flow solver * Temperature solver * Basal hydrology solver * Ancillary solvers (e.g. vertical velocity)

code development
Development strategy for various aspects of the project to be discussed here.


 * We intend to implement nested grids.


 * If we move the solvers to a set of libraries we'll need to define an API.


 * The glimmer ice sheet model may require further development in order to build in the higher order code from glam and to allow for nested grids.

surface mass balance

 * Day-degree model


 * Energy balance model

Ice-ocean interaction
Comments on plume model.

ESM/GCM coupling
The icesheet model will provide an interface for coupling to climate and earth systems models, probably making use of glimmer. In particular, the ice sheet model will be coupled to the Hadley Centre and Los Alamos GCMs.

Observational data
Geometry

Geology

Boundary conditions

 * Surface air temperature
 * Precipitation

Model/Code Development
Relevant pieces of code. Pieces of existing code that may contribute to this project.

Software development plan. This is the place to discuss which pieces of code we should use, which development strands will need to be split or merged, which existing codes can be made more modular, which need to be maintained etc.

Good coding practice/guidelines for code development. This is the place to discuss which compilers we should use, version control, how to implement simple tests to make our development process more robust etc.


 * Here is an article about good coding. You can easily find many more.  The main point is that by spending a little extra time during development adopting a pragmatic programming approach one can greatly reduce the amount of time one has to spend later on trying to debug or expand the code in the future.


 * Linux vs MS Windows. Both operating systems have their advantages for those wanting to develop fortran code.  We discuss the advantages/disadvantages here.

Current issues. Discuss ongoing debugging, development and testing issues here. Or just about anything that's bothering you.


 * DAGW, SP and RG are currently trying to make glam more portable accross compilers, and implement a simple test. Several issues relating to corss compiler differences and other bugs have arisen.

testing math...


 * $$ \rho_s c_s d \frac{dT_s}{dt}= L^{\downarrow} - L^{\uparrow} + Q_S + Q_L + Q_D + (1-\alpha)S $$
