Time series of MODIS-Aqua 8-days Suspended Particles Matter (SPM) composites from 2012 to 2016 for the northern Gulf of Mexico

Level 1 Moderate Resolution Imaging Spectroradiometer (MODIS) data is processed to extract the remote sensing reflectance at the wavelength of 645 nm and binned into an 8-day composite at a resolution of 500 m. The study uses a regional ocean color algorithm to compute suspended particulate matter concentration based on these 8-day composites.一级中分辨率成像光谱仪（Moderate Resolution Imaging Spectroradiometer，MODIS）数据经处理后，提取出645 nm波长处的遥感反射率，并以500米分辨率分箱为8天合成产品。本研究基于上述8天合成产品，采用区域海洋颜色算法计算悬浮颗粒物浓度。
