对于收集的数据集周围的下加利福尼亚与叶绿素-a浓度（（chl-a））范围从0.16至11.3毫克/立方米，浮游植物色素的高光谱吸收光谱独立反演高光谱遥感反射率使用新开发的海洋颜色算法。推导出的光谱，然后与使用过滤垫技术从水样中测得的光谱进行比较，得到的平均差异为21.4%。这些结果表明，反演算法工作得很好，为沿海沃茨观察，并建议使用高光谱遥感检索叶绿素a和其他辅助色素的潜力。
For a data set collected around Baja California with chlorophyll-a concentration ((chl-a)) ranging from 0.16 to 11.3 mg/m3, hyperspectral absorption spectra of phytoplankton pigments were independently inverted from hyperspectral remote-sensing reflectance using a newly developed ocean-color algorithm. The derived spectra were then compared with those measured from water samples using the filter-pad technique, and an average difference of 21.4% was obtained. These results demonstrate that the inversion algorithm worked quite well for the coastal waters observed and suggest a potential of using hyperspectral remote sensing to retrieve both chlorophyll-a and other accessory pigments.
