OpenDA: A High Performance Data Assimilation Toolbox

The OpenDA (Open Data-Assimilation) software reduces both development and computing costs significantly in observation models. Data-assimilation pulls the computer model results close to the available observations. Thus, the model better matches the actual situation and consequently gives better predictions than without data assimilation.

OpenDA offers a set of building blocks that allow the implementation data-assimilation for an arbitrary model with relatively little effort. The building blocks can be reused again and again and are tested with each new application. Therefore, over time they will be largely error-free. On top of that, the building blocks are optimized for high performance computing.
