##  Session Charge(Meeting web site – Detailed Agenda – Purpose and Core Questions + Mission Description)

**Breakout Session I—Science Enabled by New Measurements**
- Purpose:
- 	Consider scientific questions and issues that will be addressed by planned space-based observations. An opportunity to learn about what the Orbiting Carbon Observatory (OCO) and the missions recommended in the NRC's Decadal Survey will enable through their measurements. Sessions will provide background on mission specifications and planning, but focus on science enabled by the measurements. Sessions will provide an opportunity to identify opportunities and recommend new studies plus raise issues or concerns to be addressed by the Focus Area.
- Most sessions will start with brief, invited presentations:
- 	Anticipated scientific uses and payoffs of the planned new measurement/mission (10-15 min.)
- 	New mission (or missions), what was learned in any relevant NASA mission concept studies (10-15 min.)
- Science Enabled by New Measurements of CO2- double session spanning
- 	Breakout Sessions I and II (2:30-6:00 pm)

##  Breakout Session I Discussion(2:30-4:00 PM, except CO2 session)

- Questions:
- What are the priority science uses of the new measurement(s)? (Participants may choose to confirm/validate existing science questions/applications and/or may identify new uses)
- What do we need to do scientifically to use these new measurements and/or to get ready for the mission?
- Are there any major issues to be resolved before this science is enabled, and if so, what are they and what needs to be done?
- Note:
- 	Co-chairs of each session should identify a Rapporteur
- 	One co-chair will be responsible for reporting out (5 minutes) from the 	Breakout the next day
- 	Please adhere to schedule as presented, only one Breakout session spans the 	afternoon
- 	Full breakout reports are to be posted on the breakout session's discussion forum when 	complete, ideally prior to the plenary presentation of the breakout summary

##  Session Charge(4:30 – 6:00 PM)

**Breakout Session II — Data Records and Related Observations**
- Purpose:
- 	Consider scientific questions and issues being addressed by existing space-based observations (mainly systematic observations) and other existing or new suborbital observations. Discuss current time series data products and their scientific applications, and consider their future as Climate Data Records (CDRs) and/or Earth System Data Records (ESDRs). Discuss calibration/validation, airborne science, *in situ* observational needs for the Focus Area and/or its program elements. Identify opportunities and recommend priorities, raise issues or concerns to be addressed by the Focus Area.
- Most sessions will start with brief, invited presentations on:
- 	Data products/records to be discussed and questions/issues to be addressed
- NOTE: A breakout session on CDRs/ESDRs that was originally scheduled for Breakout Session II has been moved to Breakout Session IV (Wednesday, 11:00 am) so that scientists interested in the time series data products that constitute
- 	the Focus Area's CDRs/ESDRs can attend both sessions.

##  Breakout Session II Discussion(4:30 – 6:00 PM)

- Questions:
- What does the carbon cycle and ecosystems community expect of this effort?
- What are our biggest challenges in this area, and how do we address them?
- Is our list of identified data records complete, or is something missing?
- Does the carbon cycle and ecosystems community need to establish priorities for these and other activities, and, if so, how should they be established?
- Note:
- 	Co-chairs of each session should identify a Rapporteur
- 	One co-chair will be responsible for reporting out (5 minutes) from the Breakout the 	next day
- 	Please adhere to schedule as presented
- 	Full breakout reports are to be posted on the breakout session's discussion forum when 	complete, ideally prior to the plenary presentation of the breakout summary
- 	The FORUM and how to use it
