3. 3 NextGen 101 What exactly is NextGen??? Air transportation network which stresses adaptability by enabling aircraft to immediately adjust to ever-changing factors such as: weather, traffic congestion, aircraft position via GPS, flight trajectory patterns, and security issues By 2025, all aircraft and airports in U.S. airspace will be connected to the NextGen network and will continually share information in real time to improve efficiency, safety, and absorb the predicted increase in air transportation NextGen was enacted in 2003 by President Bush and Congress. In this initiative, the Joint Planning and Development Office (JPDO) is responsible for managing a public/private partnership to bring NextGen online by 2025 JPDO coordinates the specialized efforts of the Departments of Transportation, Defense, Homeland Security, Commerce, FAA, NASA, and the White House Office of Science and Technology Policy What exactly is NextGen???

4. 4 The 8 Key Capabilities

5. 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 "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 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 "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. 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 “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.

19. 19 The Roadmap Ahead 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 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

20. 20 The Roadmap Ahead 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 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

26. 26 The “Consistency” Issue The FAA requirements consider consistency just as important as accuracy Consistency Challenges: Spatial Internal “Representativeness” The FAA requirements consider consistency just as important as accuracy Consistency Challenges: Spatial Internal “Representativeness”

27. 27 The “Consistency” Issue Today our forecasts can send conflicting information to our customers: Public: This Afternoon: Showers and thunderstorms likely. Mostly cloudy, with a high near 84. West wind around 8 mph. Chance of precipitation is 70%. New rainfall amounts between a tenth and quarter of an inch, except higher amounts possible in thunderstorms. Aviation: KXXX 271723Z 271818 17007KT P6SM FEW090 BKN140 FM2000 28010KT P6SM VCTS BKN040CB BKN100 FM0100 32012KT P6SM SCT035 BKN100… Today our forecasts can send conflicting information to our customers: Public: This Afternoon: Showers and thunderstorms likely.

28. 28 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

29. 29 Convective Modeling Aviation requirements are demanding higher resolution models Convection in the short term time frame…0-2 hours (tactical) and 2-8 hours (strategic)…is key 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 Aviation requirements are demanding higher resolution models Convection in the short term time frame…0-2 hours (tactical) and 2-8 hours (strategic)…is key 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

30. 30 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

31. 31 Uncertainty Information Using probabilistic forecasts From the JPDO Weather ConOps… “Uncertainty in meteorological phenomena that have significant impact on system capacity is managed through the use of probabilistic forecasts. These forecasts are in a quantitative format, covering location (three-dimensional space), timing, intensity, and the probability of all possible outcomes…” Are we ready for this? Do we understand the difference between probabilistic forecasts and deterministic forecasts? Does “Stormy” give you a probabilistic or deterministic forecast?

32. 32 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 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

33. 33 Summary There are many existing initiatives that will be leveraged/expanded on as we move toward the initial WIDB and/or the 4-D Wx SAS The WIDB will clearly have benefits to NOAA and the NWS beyond aviation There are many critical science issues and challenges ahead Any questions?
