Citing PDAF

With respect to science, please cite PDAF, when you publish work obtained using the software.

A good reference on PDAF is Nerger and Hiller, Software for Ensemble-based Data Assimilation Systems - Implementation Strategies and Scalability. Computers and Geosciences, 55 (2013) 110-118, but citing the paper discussing the filter algorithm you applied would also be nice (see the page on publications and presentations).

We also enjoy to hear from you when you publish work using PDAF (See Imprint for contact information.) We have a list a publications by PDAF users and adding your publication is easiest when you notify us about it.
