JCSDA Summer Colloquium on Data Assimilation
Stevenson, Washington

July 7-17, 2009

Sponsored by the JCSDA
Coordinated by USRA Huntsville Program Office, Universities Space Research Association

The NASA/NOAA/DoD Joint Center for Satellite Data Assimilation (JCSDA) held a Summer Colloquium on Data Assimilation in 2009 engaging graduate students and individuals with early postdoctoral appointments in the science of data assimilation for the atmosphere, land, and oceans. The program included lectures by internationally recognized experts in data assimilation and an opportunity for students to interact with the lecturers in an informal setting. The objective of the program was to foster the education of the next generation of data assimilation scientists.

Colloquium Topics

The following topics were covered during the Colloquium:

• Data assimilation fundamentals including variational and ensemble techniques
• Satellite data applications including infrared and microwave
• Overview of atmospheric, ocean, and land data assimilation
• Overview of the global observing system
