Welcome to PDAF - the Parallel Data Assimilation Framework
| |||
|
The Parallel Data Assimilation Framework - PDAF - is a software framework that simplifies data assimilation with existing numerical models. PDAF reduces the work required for the implementation of the data assimilation program. Thus, users can obtain a data assimilation system with less work and can focus on applying data assimilation.
PDAF provides fully implemented and optimized data assimilation algorithms, like LETKF and LSEIK. The Framework is optimized for the application with large-scale models that usually run on big parallel computers. However, it is also well suited for smaller models and even toy models.
PDAF provides a standardized interface that separates the numerical model from the assimilation routines. This allows to perform the further development of the assimilation methods and the model independently. New developments on the algorithmic side can be readily made available through the interface such that they can be applied immediately with existing implementations.
PDAF is an open-source project. Its functionality will be further extended by input from research projects. In addition, users are welcome to contribute to the further enhancement of PDAF, e.g. by contributing further assimilation methods or interface routines for different numerical models.
