China Coastal Phytoplankton Absorption Coefficient (2003-2022)

This dataset covers two decades (2003-2022) of phytoplankton absorption coefficients at 443nm (aph(443)) in Chinese coastal waters (water depth rs) using newly enhanced coastal aerosol models in combination with NASA’s standard atmospheric correction methods. The resulting aph(443) values were then retrieved through the QAA_V6 algorithm. Based on 43,476 MODIS Aqua daily images at 1km resolution, the dataset was processed to produce a monthly median composite of aph(443) values.

本数据集借助新改进的近岸气溶胶模型结合美国国家航空航天局（NASA）标准大气校正方法，获取了2003至2022年共二十年间中国近岸海域（水深rs）443nm波段的浮游植物吸收系数（aph(443)）数据。所得的aph(443)数值随后通过QAA_V6算法完成反演。本数据集基于43476幅1km分辨率的MODIS Aqua每日影像，经处理后生成aph(443)数值的月度中值合成产品。
