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
- 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
- ??
