  1. Radiometry Updates 7/29

  2. Test 1: All Sensor Test • ‘Same’ dock location for WISP, SAS base, and buoyed HyperPro • SAS Ed sensor located on upper dock Test 2: Ed Sensor Test • Same dock location for all sensors Test 3: Water Splash Test on HyperPro • Ran HyperPro for 1-2 minutes normal • Ran HyperPro for 1-2 minutes after splashing water on the upwelling radiance sensor Dock Test 7/27

  3. WISP Test 1: Every 30 seconds for 5-6 minutes Good Agreement with Time (Some boat wakes and waves) ‘Kick’ in 750-800 Smaller

  4. Test 2: Ed Test 1: All Sensors • Good Agreement of Ed values with Time • Used Median Values To Compare with SAS/Pro

  5. Test 1: SAS Ed Sensor On Upper Dock Difference Can Be +10%

  6. Test 2: SAS Ed Sensor On Lower Dock Difference ½ As Big

  7. Test 3: Ed Pre-Splash Test (Some Waves)

  8. Test 1: Variability in Lw and Rrs

  9. Test 3: Variability in Lw and Rrs Slightly Better with Ed Sensor Closer

  10. Test 1: Variability in Lt and Lsky

  11. Test 3: HyperPro Splash Test

  12. Let’s Make It More Complicated-Immersion

  13. Let’s Make It More Complicated-ρsky=0.09

  14. Recommendations? • Keeping in mind that the SAS and/or Pro may have calibration issues, using WISP in open water doesn’t look promising ‘as is’* • Gimbal the WISP • Put a level bubble on the under side of the WISP • Add automatic sampler feature (every x seconds)

  15. EXTRA FIGURES:WISP
