  1. David Ruth Meteorological Development Laboratory National Weather Service, NOAA NOAA System-of-Systems Workshop October 2009

  2. The NWS Strategic Plan - 1999 • Deliver a credible, timely, and relevant suite of seamless weather, water, and climate products and services which exploit technology to the fullest to meet customer and partner needs. • Post NWS products and data on the Internet in graphic-oriented format (2002) • Prepare and disseminate NWS forecast products in digital form (2003)

  3. The National Academies - 2003

  4. National Digital Forecast Database (NDFD) • Contains a seamless mosaic of NWS digital forecasts • Is available to all users and partners – public and private • Allows users and partners to create wide range of text, graphic, and image products

  5. How is NDFD Produced? National Centers Model Guidance • Detailed • Interactive • Collaborative Grids Local Digital Forecast Database Field Offices National Centers Collaborate Data and Science Focus NWS Automated Products User-Generated Products National Digital Forecast Database TODAY...RAIN LIKELY. SNOW LIKELY ABOVE 2500 FEET. SNOW ACCUMULATION BY LATE AFTERNOON 1 TO 2 INCHES ABOVE 2500 FEET. COLDER WITH HIGHS 35 TO 40. SOUTHEAST WIND 5 TO 10 MPH SHIFTING TO THE SOUTHWESTEARLY THIS AFTERNOON. CHANCE OF PRECIPITATION 70%. Digital Text Graphic Voice

  6. Current NDFD Elements MaxT, MinT Weather, Wind, Wind Gusts Sky, PoP12, QPF, Snow Hazards, Convection, Climate Outlooks Temp, Dew, AppT, RH Wave Height, Tropical Winds

  7. Role of NDFD in Decision Support Services Tier 5 Tier 4 Tier 3 Tier 2 Tier 1 General Access to NWS Information Sector-Specific Decision Support Information Organization- Specific Decision Support Information Group Decision Assistance Individual Decision Assistance NDFD WHAT NWS Provides in Each Tier Standard NWS information products and services for a broad set of needs Standard NWS information products and services for a group of users with common interests Standard NWS information products and services for a specific organization (usually a government agency) NWS expert(s) who interact directly with a group of decision makers and/or information providers in a specific decision context NWS expert(s) who interact directly with and support an individual decision maker in a specific decision context

  8. NDFD in NextGen Era NextGen • “All support facilities will have a common forecast and communications toolset of hardware and software, including the NWS National Digital Forecast Database (NDFD). The NDFD is a step toward the NextGen 4D Weather Cube.” • “We currently have a National Digital Forecast Database (NDFD) and a National Digital Guidance Database (NDGD), the foundation and building blocks for moving forward into the NextGen era.” excerpted from NWS response to FAA’s CWSU Requirements Document May 9, 2008

  9. New NWS Flagship Service “The NDFD is now our flagship service, so we need to ensure it provides the most accurate and current information possible. “ Mary M. Glackin, Acting Director, National Weather Service NWS Focus - July 5, 2007

  11. The Unlimited Reach of NDFD Real Estate Data Civil Aviation HAMweather Univ of Texas Astronomy • GRIBv2 • 100,000 files/day • ~200 users • SOAP/XML • 2,000,000 requests/day • ~10,000 users Energy Production PASDA Map Services Dow Home Products Weather Bug Web Icons Shareware Chumby Federal Agencies Hurricane Alley QuickCast Weather Central TV Custom Weather The Weather Network FORECA Fire Danger Agricultural Weather AccuWeather Armed Forces ESRI GIS State Government Google Maps Weather Underground nowCOAST University Research Hydro One

  12. IT Infrastructure and Major System Interfaces • NDFD Central Server System (CSS) consists of three dual-server clusters. • 2 redundant clusters at AWIPS Network Control Facility (ANCF) • 1 cluster at AWIPS Backup Network Control Facility (BNCF) • Two sources of data to NDFD CSS • WFOs – IFPS Service Backup netCDF files via SvcBu rsync servers • NCEP – GRIB2 from TPC, SPC, CPC, and EMC; text from HPC • Three sinks of data from NDFD CSS • Telecommunications Operations Center (TOC) – GRIB2 , XML • NWS Web Farm – GRIB2 • River Forecast Centers (pulled via AWIPS WAN) – GRIB2

  13. Primary NDFD cluster db1-emix ap1-emix Secondary NDFD cluster db2-emix ap2-emix RFC (13) WFO (120+) NCEP AWIPS WAN IFPS Service Backup Servers Internet Partners & Customers NDFD Data Flow AWIPS NCF LAN NAS NWS Web Farm NWS TOC

  14. NDFD Standards and Format • Grid forecasts • netCDF (from WFOs) • GRIB2 via HTTP and FTP • Point forecasts • Digital Weather Markup Language (DWML) via SOAP • Web Feature Service employing OGC standards • Tabular XML Products (TPEX)

  15. NDFD Development • Spatial resolution that better resolves complex terrain • 2.5km 4th quarter FY10 • Hourly temporal resolution (#1 customer request) • More frequent than hourly updates • Additional forecast elements • Fire weather (3rd quarter FY 10) • Probabilistic • Digital forecasts from NCEP service centers • 4D grids capable of supporting Next Generation Air Transportation System
