- Signal-to-noise is good fo
- 2nd derivatives for coastal waters
- Blue and green light ratio
- Atmospheric corrections
- Deals well with coherent noise but not random noise
- 4th derivatives can even be beneficial, slope
- Tested
- Sentinel-2
- Work well for turbid waters (just adds in radiance)
- Ocean color biased for MSI
- Requirements
- 2nd derivative for SeaWiFS, Aqua, MOBY
- Saturation, avoid in orbit
- Calibration between satellites, have a different source
- Need key reference bands

- Go-pro camera
- 60 000 ft
- No regulations for under 4 pounds, but you are liable
- Possible retrieval
- PongSat payloads (in ping pongs), student-led
- Radarreflector experiment

- Landed in Parkfield
- Go across the bay to Selenas
- Lunas TechEdSat

- Requirements
- Ground ops/safety
- Flight ops
- Formality and verification sequences
- Soarex-8 mission
- EXO-brake deployment
- Transmit video
- Optical sensors Raphe
- HICO
- OLCI
- MODIS/MERIS
- Spatial resolution matters
- Sitting on a internal wave field (SAR)
- Why are patches of chl-a there, fronts wave currents
- Behavior of organisms
- Using 2 satellites
- Dynamics over time. 09:08, 10:06, 11:24, 12:38
- True color composite picking up tide, headwall imaging spectrometer
- Spectral shape algorithm, problematic with different algorithms
- Subtle changes in spectral shapes
- Predicting toxic blooms, not sensitive to data.
- Hydrolight, interpolator
- 3 dominating species 97% of composition
- Noise matters
- Need 10 nm as with AVIRIS
- Chl-a to carbon ratio – KELP. Experience in stress
- Applied to LandSat 8
- Co-authorship
- Calibration talks on
- Care more about the shapes
- Bio-optical algorithms need atmos. correction
- Error-bars to ground truth
- Temporal resolution important
- Corrections should be validated with ground truth, raw data
- Jaime
- Different habitats geographically
- Initiation of toxic bloom is difficult to predict
- Impact of upwelling
- High concentration of cells or Chl-a not necessarily a correlative factor to domoic acid concentrations
- Blue goes deeper in water
- Optics don’t answer everything
- Liane
- Skyradiance, solarradiance and total radiance radiometer
- HyspIRI Airborne Flight Plan
- Steve: look into the measurements
- Mission design look into the availability of observation of target
- Launch capability to stay on target
- Characterizing SNR important, specs are not good from manufacturers
- Binning pixels trade-off for worse spatial resolution to higher SNR and spectral resolution
- RESONON, trade between spatial vs. spectral
- Fix with the optical resolution in movement with satellite
- Steve
- Narrowing down on the spectral bands for what you are looking for
- Stray light corrections/calibration
- 2nd order light problems – look for Rick and
- Get a scientific measurement validity on what you are looking for
- Major work to be done on calculations
- Kanna:
- Ocean community is easy to “convince” and work with
- Collaboration with Norway
- Columbia wants to have measurements in the Arctic
- Steve and Rick
- Bigger problem with view angle than sun angle
- Periods of time with clouds
- When clouds then deploy other assets (UAV/AUV)
- Complementary system and observations for SmallSat resolution
- Need all of the components in practical point of view
- Solar-zenith angle of 10-15 degrees gave same answer for observations, Alaska
- Diffuse scattering of the ocean
- 100 km in lake for bloom
- Sensor calibration
- Using the red important for corrections, UV data perhaps
- Green peak SNR ok, but then blue is 1/10th of that
- Have a dedicated radiometer, get the PSNR, block out the green to see noise characteristics of the other aspects
- Use micro-radiometer for signature detection (dedicated)
- Corrections for aerosols etc.
- Liane
- Enough with radiometers but also use imaging spectrometer
- Norsat 4 payload, open for other possibilities (HIS just one of candidates)
- Multiple radiometers (19 channels) + HIS
- Alignment for ocean color
- Steve:
- Cannot integrate longer than as in radiometer
- Shot noise
- Filter the green
- Use HICO to complement raw data from our HIS (given a piggyback on NorSat-4 launch)
