- Downlink L1a data as baseline raw data, not L0 or L1b.
- Do most data processing on ground. E.g. L1a->L1b->L2 on ground.
- Each frame needs all ancillary data (altitude, camera settings, attitude, viewing angle, sun angle etc.)
- Radiometric processing onboard is too ambitious and will probably not work/give a lot of errors, wisest is to do it on ground
- It is advised that also geometric processing (geo-referencing etc.) should be done on ground with reference grid
- Use wide FoV RGB camera for validation and georeferencing
- Separate clearly minimum and full success criteria
- Slew maneuver should be full success criteria, Nadir imaging minimum.
- Make an objective to monitor same target area and biological matter over time, see how spectral response changes wrt chl-a concentrations
- Don't avoid atmospheric correction, we could use methods such as spectral shape identification (ref. Rick Strumpff's operational methods) and ground truth etc. but compare the results don't just go for one.
- Don't rely on ground truth for space remote sensing.
- Do ballon balloon test.
- Develop and use cloud screening algorithm (based on MeteoSat weather data).
- We should talk more with Ivona Cetinic and Susanne Craig. They have good ideas what to do in radiometric processing chain and how to interpret the data.
- Gene C. Feldman has offered to give guidance and inputs.
- Distribute data to GSFC when we get results - they can give some inputs to analysis and how to visualize it in SeaDas - but only for L1a data. Not interested in highly processed data.
