GHRSST-PP Builds on EO complementarities
DataMerging
(A. Harris)

• Polar Orbiting infrared has high accuracy
  spatial resolution

• Geostationary infrared has high temporal
  resolution

• Microwave Polar orbiting has all-weather
  capability

• In situ data provide reality in all weather
  conditions

• Access to more SST observations should lead to
  increased resolution, accuracy, stability
• Should lead to better NWP, hurricane prediction,
  ocean modeling, air-sea interaction studies,

GEO Action DA-06-03

• ACTION DA-06-03
• Demonstrate the application of the next
  generation SST observations provided by
  GHRSST-PP.
• Activities include
• Use ensemble techniques to derive SST product
  uncertainty estimates
• Improve output from ocean and atmospheric
  forecast systems through data assimilation
  techniques
• Organize and hold a series of focused working
  sessions/seminars for users and producers of SST
  data.

Long term SST user requirements

• Sustained meaningful products
• Sustained and adaptive-user driven services
• Confidence in products and delivery (new
  instruments)
• Ease of access, easy documents
• Standards, nomenclature, symbology
• A forum and community to develop (Science Team,
  UCM)
• A responsible, mature dependable community
  GHRSST-PP supporting agencies now have a big
  responsibility
• Buy in from international agencies

52
Future the Valley of Death

Changes
54
GHRSST-PP Where are we now?

• Delivering L2P, L3P and L4 products
• Integrated data products for new apps
• Services in place and evolving led by users
• Common language, nomenclature, symbology
• Well federated community
• Growing user and producer community
• Operational uptake
• Support and buy in from Operational Centre's
• Dependency on observations and analyses
• Reanalysis strategy and activities in progress
• Mature, effective Science Team
• Science groups tackling on-going issues
• Tackling SSES uncertainty estimates
• Diurnal variability, data management

55
Growing up and adolescenceComments from Neville
Smith, 2007)

• 4 things at the GODAE Ispra Meeting
• Testing of data sources
• DDS, data assembly
• Inter-comparisons
• Data assimilation
• The GHRSST-PP community has tremendous respect
• The challenge for the future is integrating
  GHRSST-PP outputs into climate, NWP and Ocean
  Forecasting products
• Surface fluxes remain the weakest parts of these
  systems
• GHRSST-PP should consider the application of its
  products
• Continue to strengthen application links and
  provide excellent scientific inputs and support
  to the community

56
Developments in progress

• Actions in Australia new vigour for SST based
  on successful experience in BRAN
• Global high-res analysis
• Assimilation experiments
• NASA call for Applications of GHRSST data
• Huge response to the call
• Discussions of an US SST Science Team
• MISST project follow on activities
• JAXA launch of GCOM-W
• Renewed interest in SST prior to launch
• China
• Collaborations with ORSI (ESA DRAGONESS/DRAGON),
  in situ radiometers, SST analysis
• Korea
• KMA interest in GHRSST activities as part of
  developing OpOc capability

57
MyOcean SST-tacGDAC

• Managed transition of Medspiration, MERSEA and
  GHRSST-PP in Europe to sustained operational
  system

Starts in 2008 with (60M total) A GHRSST-PP SST
SST-TAC will be operated Within The MyOcean
system
58
9th GHRSST-PP Science Team Meeting 2008

• The 9th GHRSST ST meeting will be held at the
  Palais des Congrès in Perros-Guirec, France
• 9th-13thJune 2008 - Please join us!
• Registration at http//www.ghrsst-pp.org

59
Sustainability GHRSST-PP -gt GHRSST

• Move from GHRSST-PP to GHRSST
• Phase-I An International pilot project tasked to
  develop and implement a distributed system to
  deliver integrated high resolution SST and Sea
  Ice (SI) data products in a sustainable
  manner(Complete)
• Phase-II Develop a sustained R/GTS system for
  SSTSI and Manage the ongoing evaluation and
  evolution of the system (matured)
• Phase-III Deliver SST SI Climate Data Records
  (CDR) in support of WCRP, GOOS and GCOS climate
  objectives (Underway)
• Phase-IV Transition to self sustained activities
  supporting operational communities (in progress)
