2016-2020年全球海洋0.09°遥感反射率逐日数据

遥感反射率（Remote Sensing Reflectance，Rrs）是入射到水面的下行光和经过水面返回到某一方向的值之间的比率，单位为Sr-1。是水色要素（叶绿素浓度、颗粒有机碳、初级生产力等）遥感反演最重要的输入参数。
对Rrs多源遥感数据进行了波段转换预处理和质量控制，基于简单平均法，利用MODIS、VIIRS和OLCI 等Rrs遥感数据，生成了2016年~2020年全球海洋0.09°分辨率每日Rrs遥感数据产品。

Remote Sensing Reflectance (Rrs) is defined as the ratio between the downward incident light onto the water surface and the light returned from the water surface in a given direction, with the unit of Sr⁻¹. It serves as the most critical input parameter for remote sensing inversion of ocean color parameters, including chlorophyll concentration, particulate organic carbon, primary productivity, and others.
Multi-source Rrs remote sensing data were subjected to band conversion preprocessing and quality control. Based on the simple averaging method, and using Rrs remote sensing data from sensors including MODIS, VIIRS, OLCI and others, a daily global ocean Rrs remote sensing data product with a spatial resolution of 0.09° was produced for the period from 2016 to 2020.
