Use of the Polarized Radiance Distribution Camera System in the RADYO Program

摘要

The spectral polarized radiance distribution provides the most complete description of the light field that can be measured. However, this is a very difficult parameter to measure near the surface because of its large dynamic range, changes in the sky, and waves at the air-sea interface. To measure the Stokes vector of the light field, which describes the polarization of the light field, requires the combination of four images, all of which must be obtained simultaneously. To achieve this, we recently developed the Downwelling Polarized Radiance Distribution Camera System (DPOL) under support from the ONR DURIP program. The work covered under this grant supported using this new instrument, developing a polarized sky camera, and making sunphotometer measurements during the RaDYO field programs experiments in San Diego (Scripps Pier), Santa Barbara Channel, and off of Hawaii.
