Ocean Reflectance Measurements Using Orbiting Multiband Sensors: A Review ofAccuracy Considerations

摘要

A number of platform and environmental factors contribute to the oceanreflectance measurements made from spaceborne sensors. For naval or oceanographic applications that require the use of absolute values of reflectance data, i.e., water clarity, it is important that there is good understanding of the total error budget associated with the specific oceanographic parameter being addressed. Computer modeling of the radiance detected by the spaceborne sensor, is presented as an effective method for analyzing the precision of data from previous and current satellite sensors, in addition for predicting results for future spacecraft ocean sensing systems. A simplified radiance model, including some of the major mechanisms contributing to the detected radiance values, is given for illustrative purposes.
