Remote Sensing Reflectance at 667 nm, Aqua MODIS, NPP, Gulf of Mexico, 2002-2012 (Monthly Composite)

MODIS measures the remote sensing reflectance (Rrs) at 667nm. This can be used to view very high concentrations of phytoplankton in the very surface of the water.中分辨率成像光谱仪（Moderate Resolution Imaging Spectroradiometer，缩写MODIS）可在667纳米波段测量遥感反射率（remote sensing reflectance，缩写Rrs）。该测量结果可用于观测水体最表层中浓度极高的浮游植物。
