Paper Abstract

With the highly accurate calibration requirements of ocean remote sensing, it is crucial to provide long-term in-situ measurement and validation for on-orbit remote sensors by using sea-based validation sites. However, when the laboratory-calibrated spectroradiometer is transmitted to in-situ validation sites, the measurement results are greatly deviated due to the difference between the field and the calibration environment, which directly affects the accuracy of on-orbit remote sensors synchronous calibration. In this paper, both of above water measurement and undersea profile measurement are considered. The temperature effects and stray light characteristics of common spectrometers were studied. In addition, the characteristics of the classic calculation model and optimization calculation model of immersion factor are compared and analyzed.
