dc.description.abstractLake Winnipeg is the 10th largest freshwater body in the world by area and its water quality is declining rapidly,apparently due to human and agricultural activity in the watershed. Spatially distributed water quality maps are useful for studies on the sustainability of the lake ecosystem and as a means of tracking the lake’s response to nutrient and land use management strategies. A collaborative project was initiated between Noetix Research, the Department of Fisheries and Oceans and the Centre for Earth Observations Science, University of Manitoba to generate satellite remote sensing products for water quality monitoring over Lake Winnipeg. The project complements existing in-situ monitoring programs, and will assist in the development and validation of a water quality model for the lake, as well as informing the public. Total suspended solids, surface temperature, chlorophyll-a and surface algal bloom maps have been generated from AVHRR and MODIS imagery. This paper describes the approaches and procedures developed to generate these products as an operational service for inland water quality monitoring, including atmospheric correction and surface reflectance retrieval, image re-projection, algorithm calibration based on in-situ measurements, production and web publication. Potential improvements to the water quality service using MERIS images are also discussed.en_US
