Title: NOAA Response to Report on Climate Monitoring Strategies 2002 Update


1
NOAA Response toReport on Climate Monitoring
Strategies 2002 Update
  • Gregory W. Withee Assistant Administrator
    National Environmental Satellite Data and
    Information Service
  • NOAA Science Advisory Board
  • March 20, 2002

2
Context
  • Other Climate Studies and Reports
  • Adequacy of Climate Observing Systems, NRC 1999
  • Ensuring the Climate Record from NPP to NPOESS
    Meteorological Satellites, Abbott, NRC 2000
  • Recommendations of Panel on Reconciling
    Temperature Observations, NRC 2000
  • SAB Panel on Strategies for Climate Monitoring,
    Goody, 2001
  • Climate Services Vision, Barron, NRC 2001
  • Report to SAB on Assessing Observing System
    Priorities for NOAA, Karl, NOAA Council on
    Long-Term Climate Monitoring, March 2002
  • The Need for a Climate Observing System,
    Trenberth/Karl/Spence, Bulletin of the AMS, In
    Print 2002

3
Goody Panel Background
  • Goody Panel Report delivered and accepted by the
    Science Advisory Board March 2001
  • Panel Report delivered to the NOAA Administrator
    April 2001
  • Review by Climate Observations and Services
    Program Board May 2001
  • Updated SAB on progress June 2001

4
Goody Panel Response
  • Benchmark Observations
  • NOAA supports enhanced benchmark effort and
    formation of a team to examine science issues and
    possibilities for new instruments, missions and
    techniques
  • NOAA has initiated observational series that meet
    benchmark standards, e.g., the Climate Reference
    Network and the Dobson network
  • Plans in progress to modernize existing in situ
    networks, e.g., Coop network
  • Phasing critical benchmark series most critical
    for climate prediction should be implemented first

5
Goody Panel Response
  • NPOESS Climate Data
  • Significant effort already underway to
    accommodate climate observing requirements for
    NPOESS
  • Concerns regarding cost and schedule impacts of
    NPOESS climate upgrades
  • Possibility of free fliers altimeter being
    considered

6
Goody Panel Response
  • Ties Between Monitoring and Modeling
  • Operational program for climate change
    prediction desirable and feasible
  • Generation of projections from a product
    development perspective
  • Performance assessment by skill in reproducing
    historical/paleo record
  • Improved assimilation through the Joint Center
    for Satellite Data Assimilation
  • Recognized need for new activities testing models
    against observed forcing fields

7
Goody Panel Response
  • Climate Information Management
  • Agency should . . . . provide adequate support
    for data access and long-term stewardship.
  • Data access/archive issue being addressed the
    Comprehensive Large Array-data Stewardship
    System (CLASS) initiative

8
Goody Panel Response
  • Management
  • Goody Panel recommended broad restructuring for
    climate mission
  • Climate Observations and Services Program in
    place since 2001 joint management and review of
    climate activities across NESDIS, NWS and OAR
  • The Administration is currently assessing the
    proper structure for managing the climate mission
    within DOC/NOAA as well as Government-wide

9
Goody Panel Response
  • Other Comments
  • Need for more coordination of process research
    with monitoring and modeling
  • Need to consider marine ecosystems in development
    of a climate monitoring capability
  • Cost implications of implementing recommendations
    not yet determined

10
Goody Panel Response
  • Related Work on Reconciling Temperature
    Observations
  • In December 2001, NOAA responded to 28 specific
    recommendations made by an NRC panel on
    reconciling air temperature observations
  • NOAA stated that 20 of the recommendations were
    either being done or were planned to be done, and
    5 would be done if appropriate funding were
    available
  • Only 3 recommendations were not considered
    possible either because they were too expensive
    or required major policy changes

11
20 NRC Recommendations Done or Underway
  • Avoid Orbital Drift
  • Enhance pre-launch calibration of future NPOESS
    sensors
  • Coordinated overlap of NPP and EOS/NPOESS mission
    launches
  • Use free fliers for NPOESS (contractor choice)
  • Maintain continuity from SSU to AMSU
  • Investigate the use of sensors from
    decommissioned spacecraft
  • Sustain in-situ radiosonde observations
  • Intercompare old and new radiosonde types
  • Minimize changes for in-situ observing methods
    and promote continuity worldwide
  • Maintain dense U.S. network of twice daily
    radiosondes
  • Prevent adaptive procedures compromising of
    basic radiosonde network
  • Encourage other nations to follow U.S. lead on
    this
  • Achieve radiosonde ascent to 5 hectopascal level
    (international GCOS requirement)
  • Characterize accuracy by including radiation and
    lag characteristics
  • Enhance metadata in concert with the World
    Meteorological Organization
  • Develop and update radiosonde climate data
    records
  • Explore options for next-generation atmospheric
    sounding system
  • Reinvigorate efforts to ensure long-term climate
    record

12
5 NRC Recommendations Done if Funded
  • Create Web Site for Instrument Status
  • Expand radiosonde coverage in the tropics
  • Intercompare radiosonde performance at more
    regionally representative sites
  • Research required on network design for better
    spatial density of radiosonde sites for climate
    monitoring
  • Identify critical climate data records maintain
    and document their production

13
NRC Recommendations Considered
  • 3 Which Have Major Funding and/or Policy
    Implications
  • Overlap satellites one year (however now an
    NPOESS requirement)
  • Launch on schedule, not failure
  • Enhance pre-launch calibration of AMSU sensors

14
Summary
  • The Goody Panel Report provided an excellent
    review of NOAAs climate monitoring program.
    However, this formed but one piece of a larger
    rubric of other studies and reports related to
    the U.S. overall climate observing system. As
    the new Administration formulates a new climate
    structure, it will build upon all these reports
    to enhance the nations climate observing
    capabilities.
