Forces for Change • Increasing emphasis on multi-model ensemble approaches that build on the NCEP model suite • SREF • NAEFS • Climate Forecast System (EUROSIP) • Entering the JPSS era • More rapid access to hyperspectral data • GPS soundings • Higher resolution surface radiance data • All models run within ESMF • Models run concurrently • Hybrid vertical coordinate • Coupled • Spanning all scales • Operational Earth System model – more explicit hydro, climate and ecosystems applications ESMF-based System Global/Regional Model Domain Model Region 1 Model Region 2

EUROSIP Update • MOU signed in July 2010 to include NCEP as EUROSIP partner (along with ECMWF, Meteo-France, UKMet) • The EUROSIP hindcast data files have been downloaded to computers VAPOR and STRATUS (in restricted access directories) • CPC has FY11 milestone to develop and test a seasonal multi-model ensemble forecast tool that combines CFS and EUROSIP 23
Ecosystem Prediction Predicting Sea Nettles in Chesapeake Bay Current Demonstration Ready for Transition* • Automatically generate daily nowcasts and 3-day forecasts of Sea Nettles, Chrysaora quinquecirrha, in Chesapeake Bay • Generated since 2002 • Important for water management and recreational purposes * Research initiated, developed and results demonstrated by NOS and NESDIS with regional partners and customers Predicted chance of encountering sea nettles, C. quinquecirrha, on August 17, 2007
Climate and Health in Africa Observed and Predicted Meningitis Incidence Rate in logarithmic form - Case of Burkina Faso Base Period: 1968-2005 • Collaborate with NMHS Burkina Faso on predicting meningitis outbreaks • Target countries: Burkina Faso, Niger • Preliminary results suggest NCEP reanalysis can be used to predict epidemic outbreaks • Collaborate with UMD on predicting water-borne diseases • Target countries: Angola, Cameroon, Mozambique, Senegal • Preliminary results suggest role of SST and rainfall in triggering an epidemic disease • Rainfall increase of 277 mm in 7 days, 15-22 Aug 2005 • Cholera outbreak peaks about 30 days later. Yaka et al., 2008 Observed rainfall (blue) and cholera data (red) Case of Dakar, Senegal Constantin & Thiaw, in progress
Summary • NCEP is • Strategically aligned with NOAA’s “seamless suite” of products from the “Sun to the Sea” • Continually improving collaborative forecasts – especially for extreme events • Working with NOAA on expanded responsibilities (e.g, oceans air and water quality, ecology, space weather…); success is based on interdisciplinary approach • A critical transition agent in the NOAA “research to operations” process involving observations, data assimilation, modeling, and service delivery • Actively pursuing opportunities for collaboration in research, transition to operations and operational production and delivery of services with national and international communities 26

New Building Status • The developer stopped work in December 2008 when NCWCP construction was 80% complete. • In May 2009, the developer filed a claim in Federal Court to recover “damages” from the Government. This claim was dismissed without prejudice in August 2010. In October 2010, the developer filed an appeal; resolution of this appeal is pending. • In June 2009, the developer filed for bankruptcy with the County Court. In response, the court appointed a “Receiver” to complete the project. In November 2010, the court approved the Receiver’s plan and granted the receiver permission to resume construction. • In December 2010, the Receiver filed a motion to petition the Federal Court to transfer the pending Federal appeal to the County Court. Once transferred, the Receiver can ask that the claim be dismissed with prejudice, after which construction can resumepromptly. • GSA’s goal is to reach project completion approximately 12 months after re-start of construction. GSA’s most current estimate for the building’s substantial completion is March 2012.
