对影响卫星海洋颜色产品的不确定性进行量化是确保其符合任务和科学要求的基本步骤。这项工作研究了一种方法，该方法依赖于使用具有已知不确定性的现场辐射测量数据来确定影响匹配卫星数据的不确定性。通过利用气溶胶机器人网络（AERONET-OC）海洋颜色组件的现场辐射数据，将一种先进的方法应用于Sentinel-3A卫星（OLCI-A）上的海洋和陆地颜色仪器以及Suomi国家极轨伙伴关系卫星（VIIRS-S）上的可见光红外成像仪辐射计套件的辐射数据产品。分析结果支持了所提出方法的相关性。
The quantification of uncertainties affecting satellite ocean color products is a fundamental step to ensure their compliance with mission and science requirements. This work investigated a methodology relying on the use of in situ radiometric data with known uncertainties to determine those affecting matching satellite data. By exploiting in situ radiometric data from the Ocean Color component of the Aerosol Robotic Network (AERONET-OC), an advanced method was applied to radiometric data products from the Ocean and Land Color Instruments onboard the Sentinel-3A satellite (OLCI-A) and the Visible Infrared Imager Radiometer Suite onboard the Suomi National-Polar Orbiting Partnership satellite (VIIRS-S). The results from the analysis support the relevance of the method proposed.
