GMIS - VIIRS Monthly anomalies sea surface Chlorophyll-a concentration (9km) in %

Monthly anomalies sea surface Chlorophyll-a concentration (in mg.m^-3 (log10) at 9km resolution) derived from the VIIRS sensor (Visible Infrared Imaging Radiometer Suite): Chlorophyll is a photosynthetic pigment commonly present in all phytoplankton species. It is used as a proxy for phytoplankton biomass. Chlorophyll concentration is a standard product from satellite-based optical sensors, usually retrieved from empirical algorithms using reflectance ratios at two or more wavebands.

本数据集为源自VIIRS传感器（可见光红外成像辐射仪套件，Visible Infrared Imaging Radiometer Suite）的月尺度海表叶绿素a浓度距平值，单位为毫克每立方米，经以10为底的对数转换，空间分辨率为9千米。叶绿素a是所有浮游植物物种中普遍存在的光合色素，可作为浮游植物生物量的替代指示指标。叶绿素浓度是星载光学传感器的标准遥感产品，通常通过基于两个及以上波段反射率比值的经验算法反演获取。
