IUOS and U.S. AMDAR
  • IUOS Phase I
  • Future Plans
what is iuos mission and requirements space
What is IUOS?Mission and Requirements Space
  • IUOS Mission: Cost-effectively meet existing NOAA upper-air observation requirements; and future validated requirements for:
    • Improved spatial, temporal, and spectral resolution
    • New observations of environmental parameters
    • Data Management and Communications (DMAC)
  • Upper-air observation requirements space:
    • Geographical Extent: Global
    • Vertical Extent: 10 m above surface to Sun
    • Temporal Range: Warnings to Global Climate Change Prediction
    • Parameters: Winds, temperature, pressure, moisture, air chemistry, reflectivity, aerosols, biology, ….
what is iuos characteristics
What is IUOS?Characteristics
  • IUOS solution characteristics – Future IUOS will be:
    • Adaptable, extensible, stable, continuous, and quality assured
    • Cost-effective – avoid unnecessary duplication
    • Serving multi-purposes - including driving Earth-system models
    • Consistent with/component of USGEO and GEOSS

IUOS Platforms and Sensors

  • Final Operating Capability:
    • “Optimal” mix of NOAA and non-NOAA observation platforms including bothin situ and remote sensors based on NOSA Architecture Principles
slide5

IUOS RequirementsMethodology

  • Collect and Validate requirements
    • Surveyed Users
    • Scientific Literature
    • “Heritage” Requirements (e.g. FMH-3)
    • NOAA CORL (Program Input)
    • Phenomenological Analysis
  • Establish Requirements Domain
    • Threshold: Minimum performance operationally useful
    • Objective: Maximum operationally useful performance

70% of all requirements satisfied with atmospheric soundings collected every 2 hours

70% of all requirements satisfied with atmospheric soundings every 75 km

IUOS RoadmapPhased Approach
iuos phase 1 regional in situ soundings radiosonde wv aircraft obs
IUOS Phase 1: Regional In Situ SoundingsRadiosonde/WV Aircraft Obs
  • In FY06-07:
    • Evaluate model response to water-vapor sensor derived data
    • Evaluate implications of
      • forecasters using different data source and,
      • reaction of broader US weather enterprise.
    • Use evaluation to develop plan for implementation
  • In FY08-09: Begin phase 1 implementation
phase 1 adaptive sounding strategy notional plan
Phase 1: Adaptive Sounding Strategy Notional Plan
  • Use alternative sounding from commercial aircraft if WV instrumented aircraft has a scheduled ascent or descent at an airport which is within:
    • XX miles of radiosonde site
    • YY minutes of radiosonde valid time
  • CONOPS:
    • Lead Meteorologist at closest WFO coordinates sounding strategy
    • Short (<3 hrs) and long term (6 month) public notices disseminated indicating product availability and associated WMO Heading and circuits
    • Soundings from aircraft publicly available in near real-time
  • Alternative sounding strategy limited to:
    • 1 of 2 sounding launches per radiosonde station (initially)
    • CONUS Non-GUAN stations
  • Outcomes:
    • Cost avoidance from radiosonde expendables
    • Redundant observations eliminated
    • Greater % of Data Requirements Achieved
adaptive sounding strategy weather enterprise input
Adaptive Sounding Strategy: Weather Enterprise Input
  • A few questions…
  • How do you currently use radiosonde observations?
  • What do you know about atmospheric observations from commercial aircraft?
  • What transition issues might you have with use of aircraft observations as an alternative to radiosonde observations?
  • How can NOAA best communication data quality issues associated with aircraft observations?
  • How does the proposed adaptive sounding strategy timeline impact you?
  • How can we recruit Weather Enterprise contacts to answer these and other issues associated with the Adaptive Sounding Strategy???
future directions commercial aircraft observations
Future Directions: Commercial Aircraft Observations
  • Now:
    • 25 WVSSII sensors on United Parcel Service B-757 aircraft since March 2005 (NOAA)
    • 60 TAMDAR sensors on Mesaba Saab 340 Aircraft since December 2004 (NASA)
    • 1,700 aircraft contributing to the U.S. AMDAR
  • Next 1-2 Months:
    • Contract award of NOAA RFP for installation and operation of Water Vapor Data from Commercial Aircraft, negotiations on-going
  • Phase 1 Implementation:
    • Data distribution issues need to be worked if data are to be freely distributed
    • Radiosonde release schedule changes and AMDAR data availability will be coordinated with U.S. Weather Enterprise
  • End-State Plan:
    • Calls for 1,600 aircraft collecting water vapor observations
    • Optimization of vertical profilers from airlines critical to allow for expansion of AMDAR and implementation of NOAA’s IUOS.
