Dock Test 7/27 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
WISP Test 1: Every 30 seconds for 5-6 minutes All Sensors Test 1, Wavelength v. Rrs 0.01 0.009 Good Agreement with Time (Some boat wakes and waves) 0.008 0.007 0.006 Rrs (1/sr) 0.005 0.004 0.003 0.002 Kick in 750- 800 Smaller 0.001 0 400 450 500 550 600 650 700 750 800 Wavelength

Test 1: SAS Ed Sensor On Upper Dock Difference Can Be +10%
Test 2: SAS Ed Sensor On Lower Dock Difference As Big
Test 3: Variability in Lw and Rrs Slightly Better with Ed Sensor Closer
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)
