Poster Blowout 2018

Note from the Director:
I would like to thank the Director’s Science Committee for putting on an amazingly successful event where scientists and engineers across Goddard shared their work and made new contacts. The interdisciplinary interactions were especially exciting and crossed all four science disciplines.

When in Rome: The GMAO Participates in the 5th International Conference on Reanalysis

One of major themes at the GMAO is “reanalysis”, a long-term, model-based analysis of multiple observational datasets using a fixed data assimilation system. exterior shot of venue This was the focus of the 5th International Conference on Reanalysis (ICR5) held in Rome, Italy between November 13 and 17, 2017.

GMAO Makes a Super Impact at Supercomputing Conference 2017

SC17, Supercomputing Conference 2017, brought together members of the international high-performance computing (HPC) community, consisting of scientists, engineers, researchers, educators, programmers, system administrators, and developers, for a technical program, tutorials, and poster sessions. NASA’s exhibit booth maintained a strong presence in the exhibit hall, partly through the contributions of GMAO staff who performed demonstrations and gave Hyperwall presentations

The Global Modeling and Assimilation Office (GMAO) works to maximize the impact of satellite observations in climate, weather and atmospheric composition prediction using comprehensive global models and data assimilation. To achieve this goal, the GMAO develops models and assimilation systems, generates products to support NASA instrument teams and the NASA Earth science program, and undertakes scientific research to inform system development pathways.

Assimilation systems have been developed for the atmosphere, ocean, and land surface. GMAO's long-term goal is an integrated Earth system model and assimilation system that treats the individual components in a more coupled and interactive manner. GMAO works within numerous national and international collaborations to support its mission.
