GMIS - MODIS-AQUA Monthly mean particulate backscattering coefficient at 443nm (4km) in m^-1

Particulate matter (particulate backscatter coefficient at 443nm, bbp in m^-1 at 4km resolution): The backscatter coefficient bbp represents the fraction of incident light that is scattered backward from its original path by particulate material in the water. The backscattering coefficient gives a good indication of the concentration of suspended organic and inorganic particles (e.g. sediments) in the water.颗粒物数据集（443nm处颗粒后向散射系数，英文全称particulate backscatter coefficient，缩写bbp，单位为m^-1，空间分辨率4km）：后向散射系数bbp指入射光被水体中的颗粒物向后散射，偏离其原传播路径的比例。该后向散射系数可有效表征水体中悬浮有机与无机颗粒物（如沉积物）的浓度。
