What OpenDA can do for you

  • Provides researchers with a tool for experimentation with data-assimilation/calibration methods without the need for extensive programming
  • Enables quick implementation of data-assimilation and calibration for arbitrary numerical models
  • No need to learn and implement many different Data Assimilation and calibration algorithms/methods
  • Successfully used in many applications and publications: e.g., eWaterCycle I & II, OpenFOAM, Clever Monitoring.

OpenDA is an open interface standard for (and free implementation of) a set of tools to quickly implement data-assimilation and calibration for arbitrary numerical models. OpenDA wants to stimulate the use of data-assimilation and calibration by lowering the implementation costs and enhancing the exchange of software among researchers and end-users.
A model that conforms to the OpenDA standard can use all the tools that are available in OpenDA. This allows experimentation with data-assimilation/calibration methods without the need for extensive programming. Reversely, developers of data-assimilation/calibration software that make their implementations compatible with the OpenDA interface will make their new methods usable for all OpenDA users (either for free or on a commercial basis).
OpenDA has been designed for high performance. Hence, even large-scale models can use it. Also, OpenDA allows users to optimize the interaction between their model and the data-assimilation/calibration methods. Hence, data-assimilation with OpenDA can be as efficient as with custom-made implementations of data-assimilation methods.
