Paper Abstract

Optical properties of sea water, such as water leaving radiance, contain valuable information about constituents of the aquatic system. Airborne remote sensing provide access to synoptic data over large spatial scales, even under cloudy conditions. However, in addition to the desired water-leaving radiance, the upwelling radiance measured aboard the aircraft contains contributions from atmospheric scattering and from reflection from the sea surface. Here, we discuss atmospheric and surface correction methodologies. Our goal was to developed a simple operational correction method for data collected during low-altitude flights that would apply to different atmospheric conditions. Remote ocean color data were collected from a low flying NOAA P3 aircraft in the southeastern Bering Sea in APril and May 1996. Shipboard observations of upwelling radiance just below the sea surface made during aircraft overflights were used as sea-truth observations. Our simple method performed well, but still has to be test with independent data.
