Satellite - Ocean Colour - MODIS - 1 day - Chlorophyll-a concentration (GSM 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 Garver-Siegel-Maritorena (GSM) method implemented in the SeaDAS processing software l2gen and described in “Chapter 11, and references therein, of IOCCG Report 5, 2006, (http://ioccg.org/wp-content/uploads/2015/10/ioc...Aqua卫星平台搭载了中分辨率成像光谱辐射计（MODIS），该传感器可在多个波长波段下观测海洋表层水体反射的太阳光。这些多光谱测量数据被用于反演水体中叶绿素a（Chl-a）的浓度，而该物质主要由浮游植物产生。目前存在多种用于估算叶绿素a浓度的反演算法。本数据集采用在SeaDAS处理软件l2gen中实现的Garver-Siegel-Maritorena（GSM）算法，相关方法详见2006年《IOCCG报告第5号》第11章及其中引用的文献（http://ioccg.org/wp-content/uploads/2015/10/ioc...）
