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

4 Steps to SAR Nirvana 1.Define science challenges 2.Assess utility/desirability of existing platforms & data sets 3.Begin with “baseline” technology – L-band InSAR 4.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

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.
