Global Modeling and Assimilation – Systems and Data Synthesis
to Advance NASA’s Exploration and Prediction of Earth’s Environment
This is a proposal to develop end-to-end systems to optimize the use
of satellite data in model-data syntheses in support of NASA’s
missions, the nation’s Climate Change Science Program, and environmental
prediction, including weather, air quality and climate prediction. The
models and assimilation systems encompass the physics, dynamics, chemistry
and ecosystems of the atmosphere, ocean, and land surface. The scope
of the proposal is • integration of systems for generation
of long-term consistent products and day to day operational products
for NASA instrument teams, for field campaigns and for analyses of the
historical climate record during the satellite era, in support of the
CCSP; • development of the infrastructure that eases experimentation
by GMAO and visiting scientists as well as JCSDA partners; • end-to-end
system integration – of components developed and integrated by
GMAO in a research framework – into an operational framework for
regular experimentation and data ingest; • collaboration with external
partners to advance the GMAO system components and integrate/couple components
needed to address priority science questions • optimization of software
for HEC architectures; • implementation of ESMF across all GMAO
models and assimilation systems and interaction with other developers
to ensure compatibility of implementation for contributed components; • scientific
evaluation/validation, with metrics defined by the priority science applications
of the GMAO, by instrument team customers, and by external partners,
and by the GMAO science steering committee; • day-to-day application
and monitoring of the systems for rigorous test and evaluation of system
performance, particularly with regards to the applications of weather,
air quality and short-term climate prediction, including tuning and quality
control of satellite data streams; • development of the infrastructure
to address observing system issues relevant to GEOSS; • documentation
and maintenance of the environmental modeling and assimilation systems. Our
objective is to build a comprehensive framework to support NASA Earth
Science modeling and assimilation objectives, both by maximizing use
of satellite data and by providing intelligent, quantitative guidance
for the development of new remote sensing technologies and missions.
Application of modeling and assimilation methodologies in this mission-support
concept is best achieved by NASA investigators with intimate knowledge
of the problems and opportunities of Earth remote sensing. The
integrated systems approach proposed here, with the accompanying tools
to support scientific validation, will enhance NASA’s commitments
to national goals in climate and Earth science in a manner that maximizes
the Agency’s unique strengths.
