- Description
- NASA/GSFC has a requirement for The Global Modeling and Assimilation Office (GMAO)at NASA/Goddard Space Flight Center (GSFC), which undertakes research and development tomaximize the impact of satellite observations in climate, weather and atmosphericcomposition prediction. Global models and their associated data assimilation systems areused to incorporate observations to improve the estimates of the state of the atmosphere,ocean, or land surface made through model simulations (state estimates). To achieve thisgoal, the GMAO undertakes model and assimilation development, generates products tosupport NASA instrument teams and NASAs Earth science program, and undertakes scientificresearch to inform system development pathways. Assimilation systems have been developedfor the atmosphere, ocean, and land surface. The long-term goal is an Integrated EarthSystem Model and Assimilation System wherein the individual components are treated in amore interactive manner. The GMAO represents NASA as one of the partners in the JointCenter for Satellite Data Assimilation (JCSDA) with the goal of accelerating thetransition of NASA satellite information into operational applications.One of the recent meteorological products generated by the GMAO is the Modern EraRetrospective-analysis for Research and Applications (MERRA) from the assimilation ofhistorical atmospheric data (from 1979 to the present). These data focus on the modernera, i.e., the satellite era. MERRA has been generated with the Goddard Earth ObservingSystem (GEOS) model, version 5 (GEOS-5) and its associated atmospheric analysis system,the Grid-point Statistical Interpolation (GSI), developed in collaboration with theNOAA/National Centers for Environmental Prediction. The GEOS-5 system software includes atool referred to as the replay which allows the ingest of an existing analysis,like MERRA, into the model as it is running in simulation mode. This replay thusconstrains the model close to the analysis as if it were undertaking assimilation. GEOS-5 is coupled with the Goddard Chemistry Aerosol Radiation and Transport (GOCART)model so that GEOS-5 meteorological states can be used to transport aerosol fields. Itis also coupled with the Global Modeling Initiative (GMI) Chemistry model so thattropospheric and stratospheric trace gases (such as ozone and carbon monoxide) can bemodeled. The replay capability of GEOS-5 allows us to simulate aerosol and chemistryvariations consistent with GEOS-5 meteorological analyses from assimilation.The task using ARRA funds will support the GMAOs activities and the support requirementsare broken down into 3 subtasks:(a)Progress towards an Integrated Earth System Analysis by undertaking simulationswith the GEOS-5 model coupled to both GOCART (for aerosols) and GMI (for trace gaschemistry), using the replay technique with the MERRA meteorological forcing;(b)Advances in the assimilation of Advanced Infra-Red Sounder (AIRS) and microwavelimb sounder (MLS) radiance data into the GEOS-5 atmospheric data assimilation system(DAS), and(c)Use of MERRA to contribute to improving cloud and convection parameterizations byplacing satellite data in a meteorological context and expanding the parameter spaceexplored by a single column model (SCM) version of GEOS-5 and cloud resolving model (CRM)simulations to be conducted by the Mesoscale Atmospheric Processes Branch.NASA/GSFC intends to award a new Task 22 under Contract No. NNG06HX04C with ScienceApplications International Corporation (SAIC).Cost plus award fee Contract No.NNG06HX04C was awarded to SAIC, on December 28, 2005, on a competitive basis. The Government does not intend to acquire a commercial item using FAR Part 12.See Note26.An Ombudsman has been appointed.
