Optical remote sensing models for estimating suspended particulate matter in the St Lawrence estuary (OSPLE)

本研究是利用可见光-近红外光谱区基于原位和星载测量的光学模型来表征圣劳伦斯河口（SLE）悬浮颗粒物（SPM）的时空分布。该项目将：(1)研究一年中不同时期SLE水面SPM浓度与光学性质（水中和卫星衍生）之间的关系，(2)确定不同SPM属性（组成、大小分布）如何解释SPM-光学关系的时空变化，以及(3)研究气候变率如何与卫星衍生SPM的年际和长期模式相关联。

This proposal is about characterizing spatial and temporal distribution of suspended particulate matter (SPM) in the Saint Lawrence Estuary (SLE) using optical models based on in situ and spaceborne measurements within the visible-near IR spectral region. This program will: (1) investigate relationships between SPM concentration and optical properties (in-water and satellite derived) of surface SLE waters during different periods of the year, (2) determine how different SPM attributes (composition, size distribution) explain time-space variability of SPM-optical relationships, and (3) examine how climate variability is linked to inter-annual and long-term patterns of satellite-derived SPM.
