HLY-02-03 In Water Radiometric Data [Hill, V.]

This data set contains data collected during the Summer SBI 2002 cruise aboard the U.S. Coast Guard Cutter (USCGC) Healy (HLY-02-03). Satlantic SPMR/SMSR #005 (profiler w/ surface reference) system measures 13 channels of upwelling radiance and downwelling irradiance simultaneously. Data are recorded at 6 Hz, and the profiler is free fall configuration with a descent target of 1 m/s. 13 channels: 400, 412, 443, 490, 510, 519, 532, 555, 566, 619, 665, 683, and 700. The SPMR/SMSR in-water radiometric data were normally collected after the Conductivity Temperature Depth (CTD) - productivity cast, within 30min. The ship was orientated to the sun during SPMR/SMSR deployment to minimize ship shadow effects. The SPMR/SMSR data were processed with Satlantics ProSoft ver 6.3d. Data products include: Upwelling radiance Lu (uW/cm^2/nm/sr) profiled and surface data, Downwelling irradiance Ed (uW/cm^2/nm) profiled, and Downwelling surface irradiance Es (uW/cm^2/nm) data.
