3. The Perfect Reference “Always turns up on time.”
“Makes a lovely cup of tea.”

4. The Perfect Reference Good on-board Calibration
Stable!
Full Spectral Characterisation
Known Field of View
Hyperspectral instruments
can synthesis any SRF
SI Traceability in orbit
Long Operating Life
In stable non-synchronous orbit
To allow good range of collocations with GEO and sun-sync LEO

5. Discussion
Are we ready to adopt a reference standard for solar channels?
What do we need to do to establish traceability?
Volunteer to review AIRS-IASI
And report at next web meeting on
What do we need to do to prepare for CLARREO?
What do we need to do to prepare for microwave?
How can we change references in future?
Topic for next web meeting – Product Consistency
