We are pleased to announce the formation of a new IAGA working group, the Geospace Data Assimilation Working Group (GeoDAWG), joint between IAGA Divisions II and III.

The broad goal of this working group is to exchange ideas and techniques on how to incorporate sparsely and/or unevenly sampled measurements into models, a problem we face throughout Geospace. Specific goals include:
• Provide a forum for groups to highlight modeling capabilities. Oftentimes disciplines may not be aware of modeling efforts in other disciplines.
• Discuss complexities of data assimilation unique to Geospace modeling, what can and cannot be adapted from other disciplines such as atmospheric modeling.
• Exchange methodologies across Geospace disciplines. What works and what doesn’t?
• Assist communication within disciplines, to overcome geographic barriers to collaboration
• Connect with groups external to Divisions II and III to learn about different numerical techniques, particularly new state of the art techniques from statistics, mathematics, computer science, and other physical disciplines.
• Share information on upcoming missions or measurements that could be of value to data assimilation modeling groups.
• Provide guidance on data sources, data reliability, & appropriateness for data assimilation. Even the best data assimilative model is only as good as the data that go into it.
• Discuss data sources that may be unique to Geospace such as remote sensing using energetic neutral atoms or auroral imaging.
If interested, please send an email to either of the chairs.
