Satellite-Based Assessment of Lake Lanier Chlorophyll A

Watch a 13-minute conference presentation from the Georgia Water Resources Conference exploring the development and testing of a new procedure for assessing chlorophyll-a concentrations in Lake Lanier using Sentinel2A/B satellite data. Learn about the innovative approach that achieves 30-meter spatial resolution monitoring through multivariate nonlinear associations between multi-band satellite and in-situ chlorophyll-a measurements. Discover how this operational tool, developed by the Georgia Water Resources Institute and hosted on Google Earth Engine, enables rapid creation of concentration maps and seasonal assessments with impressive accuracy (RMSE 0.5-1.3 ug/L). Understand the broader implications for water quality monitoring across Georgia's inland waters, as the model demonstrates potential for regional application in similar water bodies used for drinking water, irrigation, industry, and recreation.
