Comparison of satellite algorithms for water quality in the upper Manitoba Great Lakes

Through 2016-2017, we conducted open water season sampling for chemical, biological, and physical parameters on the upper MBGL. From 2017 to 2019 we collected in-situ measurements of spectral reflectance paired with water quality parameters to test possible Sentinel 3 OLCI reflectance algorithms for determination of chlorophyll-a, suspended sediment and coloured dissolved organic matter. Our goal is to develop local validation for satellite methods to be used in conjunction with in situ data to support management of these lakes as a single, complex hydrological system.

自2016年至2017年，我们对MBGL上游区域进行了开放水域季节性采样，以测定化学、生物和物理参数。自2017年至2019年，我们收集了与水质参数相结合的现场光谱反射率测量数据，以测试Sentinel 3 OLCI反射率算法在测定叶绿素-a、悬浮泥沙和有色溶解有机物方面的可能性。我们的目标是开发适用于与现场数据结合使用以支持单一、复杂水文系统管理的卫星方法的本地区域验证。
