Satellite - Ocean Colour - MODIS - 1 day - Chlorophyll-a concentration (OCI model)

The Aqua satellite platform carries a MODIS sensor that observes sunlight reflected from within the ocean surface layer at multiple wavelengths. These multi-spectral measurements are used to infer the concentration of chlorophyll-a (Chl-a), most typically due to phytoplankton, present in the water. There are multiple retrieval algorithms for estimating Chl-a. These data use the OCI method (Hu et al 2012, doi: 10.1029/2011jc007395) recommended by the NASA Ocean Biology Processing Group and implemented in the SeaDAS processing software l2gen. The OCI algorithm is described at https://oceancolor....Aqua卫星平台搭载中分辨率成像光谱辐射计（MODIS, Moderate Resolution Imaging Spectroradiometer），可在多个波长下观测海洋表层水体反射的太阳光。上述多光谱测量数据可用于反演水体中叶绿素-a (Chl-a)的浓度，其中大部分由浮游植物所产生。当前存在多种用于估算Chl-a浓度的反演算法，本数据集采用由美国国家航空航天局（NASA, National Aeronautics and Space Administration）海洋生物学处理小组推荐、并在SeaDAS处理软件的l2gen模块中实现的OCI算法（Hu等，2012，DOI: 10.1029/2011jc007395）。OCI算法的详细说明可参见https://oceancolor....
