NextGen 101 and The Weather Information Database Oct 6th, 2009 Steve Abelman Aviation Meteorology Focal Point Office of Science and Technology Overview NextGen 101 What is the Weather Information Database (WIDB) and the Single Authoritative Source Why NOAA? What are we doing now The roadmap ahead Broader benefits to NOAA Science Issues and the 4-D Cube

Summary 2 So what is NextGen? NextGen is a Congressionally mandated initiative to modernize the U.S Air Transportation System in order to: Increase capacity and reliability Improve safety and security Minimize the environmental impact of aviation 3 So what is NextGen? These improvements to the air transportation system will be achieved by applying:

Space-based navigation and integrated surveillance Digital communications Layered adaptive security Weather integrated into decision-making Advanced automation of Air Traffic Management Net-centric information access for operations 4 The 8 Key Capabilities 5 NextGen 101 Weather accounts for 70% of all air traffic delays within the U.S. National Airspace System (NAS)

The Federal Aviation Administration (FAA) has determined two thirds of this is preventable with better weather information (better content, assimilation, better consistency, etc) better "A key finding, based on an analysis of several 2005-2006 convective events, is that as much as two-thirds of the weather related delay is potentially avoidable." -Research, Engineering and Development Advisory Committee; Report of the Weather-ATM Integration Working Group; Oct3, 2007

6 NextGen 101 The total cost of domestic air traffic delays to the U.S. economy was as much as $41 billion for 2007.* Air-traffic delays raised airlines' operating costs by $19 billion. Delays cost passengers time worth up to $12 billion. Indirect costs of delay to other industries added roughly $10 billion to the total burden. *Your Flight Has Been Delayed Again; Congressional Joint Economic Committee; May 2008 7

NextGen 101 NextGen goals are not achievable without improving integration of weather information into decision support systems NextGen weather vision (a major paradigm shift) is focused on: Providing a multiple user common weather picture Consistent and reliable weather information An improved weather information data storage approach containing observation and forecast data (i.e., the WIDB or the 4 Dimensional Weather Data Cube) enabling NextGen dissemination capabilities 8

NextGen 101; Key Themes A Net-centric (net-enabled) capability is envisioned: Network Enabled An information network that makes information available, securable, and usable in real time Information may be pushed to known users and is available to be pulled by others Weather information sharing is two-way Virtual repository with no single physical database or computer Conceptually unified source distributed among multiple physical locations and suppliers, of which NOAA is the leading data supplier 9

NextGen Weather Basics Today Not integrated into aviation decision support systems (DSS) Todays requirements can lead to inconsistent info Low temporal resolution (for aviation decision making purposes) Disseminated in minutes Updated by schedule Fixed product formats (graphic or text)

NextGen (new requirements) Totally integrated into DSS Updated requirements/ Nationally consistent High temporal resolution Disseminated in seconds Updated by events Flexible formats 10 What is the WIDB? The WIDB (aka the 4-Dimensional Weather Data Cube) will contain: Continuously updated weather observations (surface to low earth orbit, including space weather and ocean parameters)

High resolution (space and time) analysis and forecast information (conventional weather parameters from numerical models) Aviation impact parameters for IOC (2013) Turbulence Icing Convection Ceiling and visibility Winds (surface and aloft) The WIDB of the future will contain all not just aviation parameters. weather data, 11 Weather

Single Authoritative TheSource? 4-D Wx Single Authoritative Source (SAS): Is only a portion of the WIDB Provides a common weather picture for National Air Space (NAS) participants (Airlines, DoD, FAA, etc.) Is the basis for all aviation decisions by Air Traffic Management (ATM) in the FAA Is formed by merger of model data, automated gridded algorithms, climatology and observational data, and meteorologist input/data manipulation to ensure consistency and accuracy 12 Definition of 4-D Wx

SAS at FOC The Single Authoritative Source (SAS) is a subset of the NextGen 4-Dimensional Weather Data Cube (WIDB) that supports the civil Air Navigation Service Providers (ANSP) Air Traffic Management (ATM) decisions. By Final Operational Capability (FOC), the SAS will: provide the optimal representation of all ANSP-used weather information that is consistent in time, space, and among weather elements be accessible to all be the source of weather information for the ANSPs ATM decisions be specified by the ANSP be network-enabled as part of the 4-D Wx Data Cube. 13

NOAA is the most logical integrator and operator of this data cube based on its: Extensive experience with data ingest and assimilation Ownership of major observation and modeling capabilities Experienced meteorological workforce Legislative mandate to provide weather to the FAA Existing related capabilities such as AWIPS and NDFD 16 Why NOAA? Integrated Work Plan Defines Our Role

NOAA stands ready to accept the role as the Office of Primary Responsibility for Weather Information Services as this responsibility is core to NOAAs mission, and we are confident that [the IWP] will enable us to better align NOAAs weather portfolio with NextGen Mary Glackin; April 7, 2008 17 So Whats Happening Now? Multi-agency initiatives: NextGen Network Enabled Weather (NNEW) IOC Development

Team coordinates teams below: Environmental Information Team Whats in the Cube IT and Enterprise Services Team Cube IT or plumbing Policy Team Governance, cost apportionment, data rights, etc Demonstration Team library of government sponsored and private industry demos Requirements Development FAA leads development of functional and performance requirements Integrated Science Roadmap NOAAs OAR leading initiative 18 Whos Who in NextGen 19

The Roadmap Ahead Initial Operational Capability (2013) Integrated environmental information sources Initial meteorologist oversight of gridded data Common data standards and protocols Network-enabled information exchange Intermediate Capability (2016) Improved modeling and science enables higher resolution more accurate information Full Network compatibility of environmental information Direct integration of weather into Air Traffic Management Systems Full Operational Capability (2022) All NextGen requirements met and benefits achieved High resolution, nested scale forecasts available for all elements Full network connectivity ensures consistent information use across service areas and user

groups 20 4-D Weather Cube Broader Benefits to NOAA Aviation driven consistency and accuracy requirements will improve all NWS services Consistency challenges not unique to aviation More accurate public forecasts because of aviation driven high resolution modeling requirements Improved severe weather lead times because of aviation driven convective forecasts

Implements Warn on Forecast technologies 21 4-D Weather Cube Broader Benefits to NOAA Improved access to all NWS products and services via the cube Supports automated decision assistance tools for other agencies and entities beyond FAA IT and Data Management enhancements Establish a central repository and access for critical NWS products and services beyond aviation

Support GEOSS requirements Enhances continuity of operations Extends the AWIPS enterprise services into a system of systems linking AWIPS, MADIS, NDFD, GOES, NEXRAD, etc 22 Science Issues and Challenges Consistency The Forecast Process Convective Modeling Model Enhancements and Improvements Verification Turning stovepipes into a System of

Systems 23 The Consistency Issue The FAA requirements consider consistency just as important as accuracy Consistency Challenges: Spatial Internal Representativeness a click inside the cube represent what I see (Does

really outside?) 24 NextGen Weather Challenges The Forecast Process: Most existing NWS forecast processes not designed to meet the resolution, refresh and latency requirements of NextGen Temporal and Spatial resolution Are NextGen observation and forecast requirements viable? Will model researchers and developers have the resources available? NOAA and research partner R&D focusing on Meteorologist-in-the-Loop (MITL) and

Meteorologist-over-the-Loop (MOTL) techniques Changing forecast process culture is complex and possibly controversial 25 Convective Modeling Aviation requirements are demanding higher resolution models Convection in the short term time frame: 0-2 hours for tactical planning 2-8 hours for strategic planning Resolution requirements based on Terminal within 100km radius of an airport, aka Super Density Operations (SDO) Enroute within the National Airspace System (NAS), aka Trajectory Based Operations (TBO)

Global outside the NAS 26 Verification NextGen suggests verification schemes that measure operational impacts Move away from traditional verification methodology like PoD and FAR An example is the Weather Impact Traffic Index, WITI Measures efficiency of the NAS operation, but weather is only one factor Factors in airport capacity, time of day, traffic corridor, etc NWS/FAA is collaboratively working on the Terminal Forecast WITI which is a forecast of the NAS operation at

a terminal or a corridor 27 27 The System of Systems Challenge Getting out the message Communicating with the FAA Building real use cases NWS support from the regions, the field, and the NCEP centers Interagency security and governance 28 Summary NextGen will require significant changes in the way

weather information is produced The NextGen paradigm suggests that most weather information will be assimilated into decision support tools and the decision making process NOAA has been designated as the Office of Primary Responsibility (OPR) to build and deploy a 4-D Weather Data Cube (WIDB) by IOC (2013) and beyond Even though NOAA is the OPR, multi-agency teams are working all the issues involved with the cube The FAA is leading the Integration effort and this is just getting started 29 Summary The WIDB will clearly have benefits to NOAA and the NWS beyond aviation There are many important science issues,

including consistency, model resolution, observation strategies, and verification which must be addressed as we move toward a comprehensive 4-D Wx Cube 30 BACKGROUND SLIDES What can we leverage. 31 What can we leverage? Aviation Digital Data Service (ADDS) Extremely popular aviation weather web service

Not just a display capability Already has many NextGen data service capabilities Data service easily capable of supporting the standards and protocols envisioned with NextGen Has existing capability to support 4D data cube Slices, dices, and returns a subset of data (flight paths or subset cubes) 32 What can we leverage? National Digital Forecast Database (NDFD)

Could be called the SAS of public weather forecast mission Net-centric approach Need to add aviation parameters in the vertical Logistically very complicated if to be populated by each WFO 33 What can we leverage? Interactive Calibration of Aviation Grids in 4 Dimensions (IC4D) Aviation weather research community (NCAR) now producing 4-D (x, y, z, t)

gridded guidance for parameters such as turbulence and icing (RUC2-based) operational forecasters may be able to add skill to the forecast guidance Interacting with a 4-D data set containing multiple parameters presents a huge challenge, operationally Alaska AAWU working with IC4D and has provided positive feedback 34 What can we leverage? Localized Aviation MOS Program (LAMP) Hourly updates of GFS MOS data for

aviation Uses hourly observations (METAR, lightning, and radar data) to update MOS guidance Statistically outperforming persistence and MOS during early forecast periods Currently have gridded probabilistic thunderstorm forecasts Moving toward other gridded products, including probabilistic ceiling height and visibility forecasts 35 What can we leverage? Auto-nowcaster a program to determine the role of

the forecaster in providing valueadded enhancements to automated, gridded aviation convective products goal is to improve the consistency, reliability, and accuracy of 0-2 hour convective forecast products for automated aviation weather digital products (4-D grids) for the NAS being considered in 2009 as part of a multi-agency NextGen demo in Florida 36
