AB: The Marine Optical Buoy (MOBY), a radiometric buoy stationed in the waters off Lanai, Hawaii, is the primary ocean observatory for vicarious calibration of satellite ocean color sensors. Since late 1996, MOBY has been the primary basis for the on-orbit vicarious calibrations of the USA Sea-viewing Wide Field-of-view Sensor (SeaWiFS), the Japanese Ocean Color and Temperature Sensor (OCTS) and Global Imager (GLI), the French Polarization Detection Environmental Radiometer (POLDER), the USA Moderate Resolution Imaging Spectrometers (MODIS, Terra and Aqua), the Japanese Global Imager (GLI), and the European Medium Resolution Imaging Spectrometer (MERIS). The MOBY vicarious calibration of these sensors supports the international effort to develop a global, multi-year time series of consistently calibrated ocean color data products. A longstanding goal of the Ocean Color Science Teams is to determine satellite-derived normalized water-leaving radiance (L_WN) with a combined standard uncertainty of 5 percent. A critical component of this approach is to reduce uncertainties in MOBY in situ L_WN data. As has been the case since the first MOBY deployment, these improvements are achieved incrementally and from a variety of system aspects. We will discuss these efforts and present results relating to the radiometric calibration, instrument stability during deployments, sensitivity to temperature, stray light corrections, data acquisition protocols, and instrument self shading.
