GEO Data Quality Strategy

• Major topics
• Characterisation and Classification of Cal/Val
  Sites
• Satellite and In Situ Cal/Val Data Access
• Methodology and Guidelines for Cal/Val
• Harmonisation of Quality Information
• Progress in 2007-2008
• CEOS WGCV ACSG meetings
• 2 GEO - CEOS Workshops (Oct. 07/May 08)
• EO Cal/Val Portal http//calvalportal.ceos.

• GSICS, AVDC, GVDC, GAS
• QA4EO

GEO Data Quality Strategy
Some ozone relevant issues

• More traceable and harmonized measurements,
  validation and quality information (version
  history, validation history, standards, caveats)
• Improve and harmonize data file content AND
  metadata averaging kernels and/or weighting
  functions (even for column data), error budget
  (systematic and random), information content
• Identification and development of best practices,
  protocols, guidelines

Harmonization Cooperative Efforts

• Aura/Envisat/ACE collaborations
• SAUNA Campaigns http//fmiarc.fmi.fi/SAUNA
• Contact Bojan Bojkov _at_nasa.gov, now at _at_esa.int
• ESA/NASA-sponsored with participation of Dobson
  and Brewer World and Regional Standards ,
  NDACC-certified UVVIS spectrometers, O3S, lidar
  and many satellites
• Issues revealed/stressed for all GB techniques
  and for comparison techniques

Harmonization Cooperative Efforts

• CEOS-ACSG/NSMC topical meeting and NOAA/NSMC
  cooperation on FY-3 SBUS/TOU
• Ozonesonde JOSIE, BESOS gt in progress
• Water vapour NASA MOHAVE gt CEOS and ISSI
  endorsed WG and campaigns, COST
• CEOS-endorsed ESA/NASA/NOAA-funded project
  5-year, calibration of Dobson, participants
  Dobson Primary World Standard, Regional
  Standards, Brewer Regional Standards,
  NDACC-certified DOAS UV-visible spectrometers
• Validation Protocols, EU Directive INSPIRE

Summary of the Key Issues

• Continuity of satellite ozone profilers
• High risk of satellite data gaps, missing
  backups, reduced capabilities under
  consideration.
• Concerns about status and evolution of GB
  networks
• Traceability and harmonization of measurements
  and QA/QC for SAT, GB, and higher level syst.
• To garantee interoperability/traceability for
  systems facing high quality requirements of
  research and monitoring, enhanced cooperation (i)
  between space agencies, (ii) within ground-based
  networks, and (iii) between GB, SAT and users, is
  cucial in the fields of calibration, level-1-to-2
  algorithms, validation, data fusion/integration/as
  similation, comminication, and education.
