PDAF enables data assimilation on high-performance computers. 

Data assimilation is used to combine observations of some system, like the ocean or the atmosphere, with a numerical model simulating this system. As both, the observations and the numerical model are not exact, the combined information of both sources can provide a better estimate of the true state of the system than each of the information sources alone.

Performing data assimilation with advanced algorithms and large-scale models is computationally extremely demanding. 


"[wiki:TracAdmin trac-admin] ''yourenvdir'' initenv" created
a new Trac environment, containing a default set of wiki pages and some sample
data. This newly created environment also contains 
[wiki:TracGuide documentation] to help you get started with your project.


Enjoy! [[BR]]
