• Should we spell out the basic GSICS principles?
– e.g. As bullet points on GCC/WMO GSICS webpages
– in response to users’ requests
– and in considering 3rd party submissions to the GPPA.
• Needs
– consideration by Exec Panel
– contribution/agreement from all GSICS members
• Some ideas for examples follow
– Need further discussion & agreement

GSICS General Principles
• e.g.
• Traceability
– Reproducibility of results
• Openness
• 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
– Continuous 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
• e.g.
• Traceability
– Inclusion of meta data giving complete description
• Accessibility
• Following community standards
– Data access (servers)
– Data formats
– Variable naming
