Any Other Business?

3. Aim
To agree common methodology to quantify the uncertainties on each method
For application to the solar channels of GEO-LEO inter-calibration
Following CEOS guidelines
To agree common qualitative criteria for assessing their performance
To identify complementary methods

4. Brief Please consider: How to apply to "your" Solar inter-cal method:
Patrice's method of Error Analysis
Fred’s Assessment Criteria
Please concentrate on these
rather than the inter-calibration method,
which will be the subject for later discussions.
What information is needed to perform this analysis?
When can we expect results?
How the error budget can be performed for multiple observations,
which may not be independent?
Should systematic biases and random errors be treated separately?

5. Conclusions
Do the uncertainty analysis and assessment criteria need further revisions?
What is needed to complete analysis?
How we will review analyses?
E.g.
GSICS wiki?
to other investigators in GSICS or external?
What is the timescale?
Next web meeting?
Next GRWG meeting?
