Meeting Goals and Objectives

Discuss and obtain agreement upon the mission-defining science requirements

Determine critical science questions and/or remaining studies needed to finalize for MCR, with schedule for completion

Determine observation requirements and/or remaining studies needed to finalize for MCR, with schedule for completion

Provide an opportunity for coordination between the mission engineering team and the science team

Provide clear understanding of the decision-making process

Team Progress: CLARREO Imperative

Initiate an unprecedented, high accuracy record of climate change that is tested, trusted and necessary to provide sound policy decisions.

Initiate a record of direct observables with the high accuracy and information content necessary to detect long term climate change trends and to test and systematically improve climate predictions.

Observe the SI traceable spectrally resolved radiance and atmospheric refractivity with the accuracy and sampling required to assess and predict the impact of changes in climate forcing variables on climate change.

Team Progress: Key Science Results

Clarification of science objectives Focus on decadal scale change

Major progress on all-sky IR benchmarking

Solar Beginning of solar OSSEs for defining benchmark Key results on information content of a radiance record Major progress on intercalibration approach Identification of polarization issues

Detailed analysis of alternative orbit sampling

What We Need

Draft Level 1 requirement document at MCR

Clearly defined science objectives

Clearly defined flowdown to observation requirements Close in the IR and GPS Need this for solar

8

How We Get There Process

Set the context for mission implementation Review current status of the CLARREO science questions and observation

requirements Review strawman mission architecture Summarize current understanding and identify issues

Expected Result Reach a decision on as many draft requirements as possible Document all input concerning outstanding issues and disagreements Identify near term actions required to resolve outstanding issues Identify critical trades for Phase A

Next Step Team will generate draft Level 1 Requirements document

Day 1 Goals

Set the context for the science requirement discussion HQ Perspective Project perspective MCR requirements Science definition status Mission Engineering

Open discussion of concerns and expectations for this mission What are the biggest risks to a successful mission? How do we mitigate these risks?

Provide clear understanding of the decision-making process

Final Thoughts

Ground Rules Recognize common goals

Commitment to getting it right

Be constructive

“Many are stubborn in pursuit of the path they have chosen, few in pursuit of the goal” – F. Nietzsche
