PDAF at the EGU General Assembly 2021

The research group developing PDAF will be present at the EGU General Assembly from April 19 to 30, 2021 online.

Short Course

SC5.14: Practical data assimilation with the Parallel Data Assimilation Framework
Convener: Lars Nerger | Co-conveners: Wolfgang Kurtz, Nabir Mamnun, Qi Tang, Gernot Geppert Friday, 30 April, 10:00 - 11:00, <a target="_blank" href="​https://meetingorganizer.copernicus.org/EGU21/session/38988">Online</a>

In this Short Course we provide an overview of ensemble data assimilation and how to apply it using PDAF.

For the hands-on example we will provide a tutorial version of PDAF that will be downloadable without registration. The download link will be announced during the short course.
