NOAA's Airborne Multispectral Measurement System (AMMS) is compared to NASA's Airborne Oceanographic Lidar (AOL) with its integral passive ocean color subsystem (POCS) by analyzing a data set collected in April 1991 over the Chesapeake Bay. In this remote sensing experiment, the AMMS and AOL were mounted on a NASA P3 aircraft that flew two passes over a study region at an altitude of 150 m, while a ship collected sea surface samples. The AMMS included a 6 channel multispectral video camera and upward and downward looking spectrometers. The AOL used a laser operating at 532 nm and a 32 channel passive radiometer. A ship gathered sea surface samples, which were analyzed for chlorophyll-a, pheophytin, and seston. The remote sensing measurements from the instruments were in good agreement when the effects of different sampling times and the different sampling areas are taken into consideration.
