GSICS Principles - Draft suggestions

These are the fundamental principles on which GSICS is based.

What do we mean when we say something "follows GSICS principles"?

Here are some ideas for further development:

GSICS General Principles

  • Traceability
    • Reproducability of results
  • Openness
    • Freedom of access
  • Applicable to operational weather and environmental satellites of the Global Observing System (GOS)
  • ??

GSICS Science Principles

  • Traceability
    • through an unbroken chain of comparisons
    • to a common reference
    • with specified uncertainty
  • Consistency
    • Applicable to all instruments in a given class
  • Systematic
    • Continous ongoing inter-calibration over each instrument's operational lifetime
  • Global
    • applicable over the full range of observations??
  • Based on level 1 data
    • as supplied by satellite operator
  • To provide inter-calibration correction function
    • to allow users to correct original level 1 data
    • to generate Fundamental Climate Data Records (FCDRs)
  • To provide bias monitoring
    • to allow users to visualise any trends in the instruments' calibration
    • ?
  • ??

GSICS Data Principles

  • Traceability
    • Inclusion of meta data giving complete description
  • Accessibility
  • Following community standard
    • Data formats
    • Variable naming
  • ??
