About ISDA-Online

The International Symposium on Data Assimilation - Online (ISDA-Online) is a seminar series on the topic of Data Assimilation.

The ISDA-Online seminar series provides a monthly online platform for the exchange of new and exciting data assimilation research. Each ISDA-Online event is a session of 2 hours with several presentations on changing topics. Usually, an event is scheduled on the first Friday of each month, but there might be exceptions in case of holidays. We alternate between 7-9h UTC and 15-17h UTC. This schedule allows us joint meetings of Europe, Asia, Australia (for 7-9h UTC), or Europe and the Americas (for 15-17h UTC). For our events, we use the software Cisco Webex Events.
