Workshop Overview

The 3rd annual Land Data Assimilation (DA) Community Virtual Workshop on “Recent Technical Developments in Land Data Assimilation” will take place Tuesday to Wednesday 20th-21st June 9am-1pm ET / 16:00-19:00 CEST.

This workshop is focused on the technical challenges of land data assimilation. To strengthen communication between modeling groups, this workshop will bring together land DA scientists to highlight a range of DA methods used within the community, address challenges facing different modeling groups, and identify strategies for addressing those challenges. The outcome of this workshop is to increase collaboration and coordination within the land DA community to tackle technical challenges and promote the routine use of DA tools in the wider modeling community. To learn more about the outcomes of previous workshops, please check out the following:

Workshop Format

This meeting will take place virtually and is free of charge. We encourage those in other time zones to register their attendance and submit an abstract for a poster. We are working on a plan to facilitate asynchronous participation from regions that cannot attend the main meeting due to time zone differences.

Call for posters: In addition to registration, we also still welcome abstracts for poster submissions. The posters should address the technical challenges associated with developing land DA systems emphasizing work-in-progress. Abstracts can be submitted through the registration link below.

Our intention is to create a workshop and community that is inclusive of participants from all backgrounds and a range of career stages. If there are colleagues who not only represent a relevant area of expertise but may also be earlier in their careers and/or from groups historically marginalized in STEM that you recommend to attend this workshop, please encourage them to register.

We are looking forward to continuing to build the Land DA Community and to seeing your abstracts!

The deadline to register is Tuesday, 13 June 2023.
