| Abstract: | In this study, we try to mi prove the understanding ofpolarization ofsignal reflected bywatersurface andwith- inwaterbody forwhich an accurate knowledge isnecessary in remote sensing applications. Polarized characteristics of the reflected light abovewater surface and the scattered light inwaterbody togetherwith their applications in ocean color re- mote sensing are reviewed. Elmi ination of the sunglintand skyglint, and inversionmethodsofpolarized ocean color remote sensing are summarized in detai.l polarization of sunglint reflected by the sea surface is routinely used to extract informa- tion in remote sensing studies, such asoil spilldetection and remote sensing ofsea state. The firstand foremost thing is to elmi inate reflected light from water surface radiance for remote sensing ofsubsurfacemateria.l The scope and lmi itationsof the efficiency ofBrewster s angle technique in elmi inating reflected light from water surface radiance is discussed forboth flat andwind roughened sea surface. Severalkey problems are pointed out, including atmospheric polarization correction, vector radiance transfer calculation, calibration of polarization sensitivity of sensor and polarization characteristics of the incident source abovewater surface, the polarization of roughened air-water surface andwaterbody. Some suggestions are put forward to mi prove the research ofpolarization information in ocean optics and ocean color remote sensing, such asde- velopmentofpredictive numericalmodels for polarized underwater radiance distribution and quantification of the relation- ship ofMuellermatrix and the concentration ofwater quality parameters. |
