- Charge to Disciplinary Groups

## OBJECTIVES (Organizing Committee)

- To re-affirm a long-range scientific and technological vision for SAR and InSAR uses in the Earth Sciences, in particular within **EarthScope**.
- Previous studies/proposals (e.g LightSAR, ECHO-x)
- EarthScope plan and NRC review thereof
- SESWG report and NRC review thereof
- IEOS Draft Strategic Plan.

## OBJECTIVES (Organizing Committee)

- To explore the diversity of disciplinary applications of a science-driven civilian SAR program:
- Identify “grand challenges” in each discipline.
- Recognize synergies between applications
- Highlight new scientific opportunities opened by SAR imaging technology

## OBJECTIVES (Organizing Committee)

- To formulate strategies for a science-driven SAR observational program:
- Assess the role of existing and planned data sets;
- Assess the needs for new data
- Address the challenges posed by data access, management and dissemination issues
- Describe usefulness and limitations of existing sensors
- Articulate the needs for new sensors

## Background and Review Lectures

-                    	*Wayne Thatcher*
- “SAR missions and new hardware developments”
-  	                     	*Paul Rosen*
- “InSAR processing and analysis advances”
- 	                     	*Howard Zebker*

## Disciplinary “Breakout” Groups

## Disciplinary “breakout” Groups

- Group Chairs and Co-chairs steer discussions, and note arguments and conclusions
- i)	What are the “grand challenges” in each area?
- ii)	How can radar sensors help address them?
- iii)	Role for existing data, sensors, new sensors
- iv)	Role of new technological advances
- V)	Education and outreach opportunities
*What are compelling scientific reasons for a dedicated SAR/InSAR observational program*

- Workshop Approach

## 4  Steps to SAR Nirvana

- Define science challenges
- Assess utility/desirability of existing platforms & data sets
- Begin with “baseline” technology – L-band InSAR
- Identify augmentations/changes needed to reach  science goals

## Breakout GuidelinesScience Breakout #1:  Drivers/Questions/Challenges

- What are the truly important and challenging science questions for your discipline that benefit from access to SAR data?
- How does access to SAR/InSAR data enable progress in each of these?

## Science Breakout #2  GuidelinesMatching Science Goals with Data and Product Availability

- Which science goals are addressable with existing/planned systems?
- access to existing data archive
- cooperative use of existing satellites
- plans for cooperative use of satellites nearing deployment
- Which science goals can only be satisfied with
- new radar missions using baseline technology (e.g., ECHO)
- added sensor capability (additional frequencies, polarizations)
-  What is the benefit of improved infrastructure?
- routine processing of derived products
- real time capability

## Summary Session Day 3:  Identifying and Prioritizing Acquisition Strategies/Needs – Report Outline

- Use of existing systems and archives to meet science needs
- Negotiated data sharing arrangements for existing and future data sets
- International cooperative experiments using existing and planned sensors (e.g., Antarctic missions)
- Role of commercial SAR data providers
- New satellite systems to advance frontier
- Major science goals
- Capabilities and technologies required
- Recommendations for the US SAR program
- Scope
- Priorities

## Slide 15

## A science-driven program?

- “Technology push” or  “Science pull” ?
- Synergies between different applications, with other initiatives, with existing/planned missions
- Long-term vision: “road-map” and strategies for an *observational program* (i.e. not a single specific mission)
- Transition from experimentation to operational observations —include long-term data curation.
