7Web-Centric Data Sharing Long-Standing Cooperative ExchangeFAA-NOAA building web servicesNOAA: NextGen IT Web Services (NGITWS)FAA: Common Support Services-Weather (CSS-Wx)FAA CSS-Wx will be:Single Source for weather to support FAA NAS SystemsNOAA / NGITWS provides NOAA weather data to CSS-WxFAA NextGen Weather Processor (NWP) provides aviation-specific weather products to CSS-WxFAA EWD: First ops web-enabled FAA-NOAA exchange[Enhanced Weather Information Network Server (WINS) Dissemination]FAA-NOAA Conducting Joint Capability Evaluations (CEs)
8NextGen Wx Vision: Providing Weather as Needed CSS-Wx provides weather information for every phase of flightTactical and Strategic time framesData may be filtered by:Location, Time and Weather parameters as requested by userThunderstormsLightningCrosswindsWind ShearFreezing/Frozen PrecipitationLow Ceiling & VisibilitySurface IcingThunderstormsLightningCrosswindsWind ShearFreezing/Frozen PrecipitationLow Ceiling & VisibilitySurface IcingThunderstorms, Jet Stream, Volcanic Ash, Turbulence,In-Flight Icing, Winds,Mountain WavesT+1T+2T+3Arrival Forecast WeatherAlternate Forecast WeatherFlight WindsT+0Post-flight observed weather archivesWhy is FAA considering CSS-Wx? [animated slide]The weather parameters listed above the flight path are not weather events actually impacting the flight, but the user is requesting data on these different parameters to enquire as to whether or not there is the threat of any of the wx parameters actually impacting the flight.8
9CSS-Wx Geospatial Data Access Services Web Feature Service (WFS):Filtered access to non-gridded data formatted as XML/GMLProvides Common Geospatial constructs for other NAS data (aeronautical, air traffic)Web Coverage Service (WCS):Filtered access to gridded data formatted as NetCDF4Uses OGC Reference ModelWeb Map Service (WMS):Image of Weather data formatted as gif, png, jpeg, etc.Web Map Tile Service (WMTS):Image of Weather data as set of tiles formatted as gif, png, jpeg, etc.What services does CSS-Wx provide?Correspondence between Services and their Data Formats
10Web Feature Service (WFS) What services does CSS-Wx provide?
11Web Coverage Service (WCS) What services does CSS-Wx provide?
12Non-Gridded Data Products Non-gridded products express singular or sparsely distributed geospatial sets of observations or forecastsContours, point products, text productsXML format and extensions used to represent non-gridded dataGeography Markup Language (GML), Weather Information Exchange Model (WXXM), etc.Geo-reference coordinates (latitude, longitude) used to represent data locationsPrecipitation ContoursStorm Motion Vectors, Extrapolated Positions, Hazard TextFronts and Fronts ForecastWhat data formats does CSS-Wx use?
13Precipitation (VIL) Mosaic Gridded Data ProductsGridded products represented as uniformly spaced observations or computed values on rectangular arraysMapping projection needed to map data grid to earth’s surfaceExamples: Lambert Conformal, Lambert Azimuthal Equal AreaNetwork Common Data format (NetCDF4) used to model gridded data productsPrecipitation (VIL) MosaicSatellite MosaicTerminal WindsWhat data formats does CSS-Wx use?
