  1. Dr. Louis W. Uccellini NOAA Assistant Administrator for Weather Services and Director, National Weather Service NOAA Satellite Conference College Park, MD April 8, 2013 NWS Readiness for GOES-R and SNPP/JPSS

  2. Building a Weather Ready Nation Building community resilience in the face of increasing vulnerability to extreme weather • Mission: • Provide weather, water, and climate data, forecasts and warnings for the protection of life and property and enhancement of the national economy • Vision…a Weather Ready Nation: • Society is prepared for and responds to weather dependent events • Success: • depends on ability to forecast and warn extreme events with enough lead time for people to plan, react, and take steps to mitigate

  3. Why a Weather Ready Nation?... Our Vulnerability to High-Impact Weather Has Increased

  4. In 2012… 14 Billion-Dollar Disasters Making the extraordinary ordinary Pre-Decisional**

  5. Global Observing System Computers (supercomputers, work stations) Data Assimilation & Modeling/Science Trained workforce Today: Everything you read, see or hear about weather, climate and ocean forecasts begins with numerical prediction models Key components of a successful forecast • Global Observing System • ~2 Billion / day • 99.9 % remotely sensed, mostly from satellites • 35 different satellites now used Satellite contribution dominated by LEO

  6. Key components of a successful Warning Services/products • situational awareness • rapid data access • increasingly remotely sensed observations • decision support services /training Satellite contribution dominated by GEO

  7. LEO vs GEO use is blurring • GEO used mostly for forecaster situational awareness (SA) • LEO used mostly for models LEO and GEO now being used in models and by forecasters for SA Pre-Decisional**

  8. Observation Impact to NWP Note: 1) Sounders on Polar Satellites reduce forecast error most 2) Results are relevant for other NWP Centers, including NWS/NCEP Courtesy: Carla Cardinali and Sean Healy, ECMWF Making the extraordinary ordinary Pre-Decisional**

  9. Proving Grounds – Testbeds – JCSDAR2O-O2R Mass loading False color for reference Effective particle radius Ash height

  10. Key Challenges • Full Integration of LEO & GEO • Operational & Research • Traditional (e.g. IR-MW) & Emerging (e.g. GPSRO) • Remotely Sensed & In-Situ • Latency • 2.5 hour data assimilation (DA) window, data loses value quickly when used in later DA cycles • Minutes latency relevant to severe weather warnings

  11. NOAA Enterprise Shared Services Model Dissemination *

  12. In Summary • Satellite data remains critically important to the forecast and warning mission of NWS • Data access / latency needs are driving integrated dissemination plans • Testbeds / Proving Grounds focused on use of GEO and LEO will have to come to grips with blurring categories of satellite data

  13. Questions?
