Data Tools for Synthesis

• Harry Stern (UW)
• Steve Williams (NCAR)
• Dmitri Nechaev (USM)
• Gleb Panteleev (IARC)
• David Kicklighter (MBL)
• Richard Lammers (UNH)
• Larry Hamilton (UNH)
• Florence Fetterer (NSIDC)

Example of data integration from CEOP
Coordinated Enhanced Observing Period

Data Tools for SynthesisShared Information

• Dmitri and Gleb consumers of data and will
  offer Arctic Ocean reanalysis data product, have
  an interest in using data that is suitable for
  data assimilation
• Richard Hydrology communitys Arctic RIMS site
  has proved helpful to many investigators, can it
  be useful for more SASS projects, or as model for
  other data tools? Can do what ifs in a group
  setting, easily. A framework for integration.
• David has seen that if you can standardize
  formats (e.g. VEMAP), it makes data much easier
  for people to access and compare results. (But it
  is not always possible)
• Harry is thinking ahead to offering SAT fields
  to others , will now try to extend fields to 45
  deg more useful to hydrologists
• Larry interested in how human dimension data
  can be incorporated as a layer in arctic maps, so
  can quickly test ideas regarding , e.g.,
  contaminant burdens and human populations

Data Tools for SynthesisConceptual or
Operational Approaches

• Avoid loosing information by processing (by
  averaging, regridding, or other manipulation)
• When possible, offer data (points, cells,
  numbers) with std dev or estimate of error, with
  time and space over which error was calculated
  included.
• Please fill out the questionnaire, for strategic
  planning purposes (May make us aware of other
  products, and will show up the range in data that
  SASS projects will produce).
• Add fields of wide interest to the ArcticRIMS
  tool, including human dimensions data. (Daily,
  or coarser, data in EASE-Grid 25 km, or by
  political units, such as counties)
• NCAR and NSIDC data managers supporting NSF
  projects will look at RIMS for features to
  incorporate in tools were working on for other
  arctic projects
• A combination of systems and/or distributed
  archives may be the best solution for ARCSS

Data Tools for SynthesisSome Possible Products

• Harry Stern and others - SAT reconstructed
  1979-present, daily, other products, monthly back
  to 1901. (100 or 25 km EASE-Grid. reconstructed,
  and global SAT. down to 50 N, Globle, on 5 deg
  lat lon.
• Andrey Proshutinsky, Jinlun Zhang, Dmitri
  Nechaev, Gleb Panteleev 3D oceanographic
  fields with 25-50 km resolution product of
  ice/ocean data assimilation (reanalysis fields).
• David Kicklighter and others Multiple
  disturbance data sets, 1700-2006. Land use data
  (row crops, pastures, timber harvest) with fire
  disturbance added, gridded to ½ deg grid.
• Probably others indicate on the questionnaire,
  please
• Note different spatial and temporal resolutions
• Format translators (provides flexibility not
  everyone can use the same format)
• Smart regridding tools
