Seed Questions:

Working Group 1

  • Should the agencies share their observation planning (at least a week plan or month plan) between agencies and how can this sharing of observation plans be organized?
  • Who will coordinate the observation planning to support specific international campaign with science and application stake holders? What is the mechanism and what are the available tools?
  • The availability of background observation data (archive data) is key to succeed to have good time series or change detection using time series SAR data. So, it is also important to share archive data catalogue information using WMT technology.
  • Is there an interest to have direct data transmission (like being investigated for ALOS-4 by Jaxa). How can the information about available ground stations be shared.

Working Group 2

  • What are the main current trends and challenges in future spaceborne SAR?
  • What are the required capabilities (coverage, revisit, resolution) for future spaceborne SAR?

    For science or application representatives, please rank your preferred capabilities:

    • 100% global coverage every 10 days, 100 m product resolution
    • 10% global coverage every 10 days, 10 m product resolution
    • 1% global coverage every 1 day, 10 m product resolution
    Please do the same as above considering wavelength. X, C, S, L.
  • To what extent does the possibility of international contributed capabilities influence Agencies’ future planning of new missions?

    As an extreme example, if your agency was planning a particular capability and another agency committed to the same capability, and permitted you equal access to the data, would it influence your decision to proceed with your plan?

  • What is the best level of coordination/collaboration between future SAR systems?

    Coordination between constellations, collaboration in the build-up of a constellation?

    Can we achieve coordination/agreements of mission requirements for future SAR systems? (different agencies providing complementary observation capabilities, standardizing observations to make them interchangeable)

  • What will be the split between commercial and public funded future SAR imaging systems?

Working Group 3

  • What initiatives are ongoing to collect regional or global data sets of field measurements of bio- and geo-physical parameters relevant to possible SAR science products?

    1. What measures are being collected
    2. How are they being collected
    3. Who is collecting them

  • What are the challenges in making these field data accessible to the broad research community?

    1. Data consistency/QC
    2. IP restrictions/protecting graduate student research
    3. Meta data requirements
    4. Etc.

  • Are there existing data portals that can be leveraged to gather these global/regional validation data sets and make them accessible?
  • How can the space agencies and missions promote joint SAR cal/val activities?

TA-1 & TA-2

  • Identify one to three SAR coordination actions that could be taken in the near/mid-term (in 2020s) that will improve science/applications overall.

    1. What communities are well served? How/why?
    2. What communities are not served? For them, what are the missing critical elements?

  • Identify and prioritize the long-term (2030+) goals and objectives for SAR coordination that would vastly improve your science discipline.

    1. Mission parameters
    2. Data / products
