Welcome …

… and Introduction:

Aim of this workshop

• Collect results (deliverables) of task 3.1.

• Identify missing things for joint assessment (task 3.2)

• Define next steps.

• Plan summary report and paper.



• Collect results (deliverables) of task 3.1. done!

• Identify missing things for joint assessment (task 3.2) done.

• Define next steps.• Consolidate common findings (lead: Silke).• In parallel: visually inspect cases with most significant

changes; perform 'recommended analysis'.• Prepare some further sensitivity studies (see next page;

lead: Axel).• Run additional sensitivity studies (maybe 5?).

• Plan summary report (and proposal for follow-up project?) and paper.



• Collect results (deliverables) of task 3.1. done!

• Identify missing things for joint assessment (task 3.2) done; deliver asap, but Fri 30 March the latest.

• Define next steps.• Consolidate common findings (lead: Silke); Fri 13 April.• In parallel, and until Fri 27 April: visually inspect cases with

most significant changes; perform 'recommended analysis'.• Prepare some further sensitivity studies (see next page)
