AQUAVERSE: ADVANCES AND VALIDATION OF AN END-TO-END PIPELINE FOR WATER QUALITY PARAMETER MAPPING IN OPTICALLY COMPLEX INLAND AND COASTAL WATERS FROM HYPER- AND MULTISPECTRAL IMAGERS
In situ sampling cannot meet the spatial and temporal coverage required for monitoring harmful algal blooms in global inland and coastal waters. While satellite remote sensing can achieve the spatial and temporal coverage required to inform in situ sampling, monitoring key indicators in these optically complex regions is complicated by fluctuations in multiple variables, including chlorophyll-a, total suspended sediment, and colored dissolved organic matter. In our work we develop machine learning models for atmospheric correction and water quality parameter retrieval specifically for these optically complex inland and coastal waters. We support a wide range of sensors, including the operational land imager (OLI/-2) on-board Landsat-8/9, the Multispectral instrument (MSI) on-board Sentinel-2, the Ocean Colour Instrument on-board the Plankton, Aerosol, Cloud ocean Ecosystem (PACE), and the Earth Surface Mineral Dust Investigation (EMIT) on-board the ISS, as well as other sensors at various stages of development. Recent advances include the addition of hyperspectral atmospheric correction algorithms for PACE and EMIT, physically-constrained water quality parameter retrieval models, water quality parameter validation in global inland and coastal waters, the addition of total uncertainty products, and improvements to our web interface known as STREAM (https://ladsweb.modaps.eosdis.nasa.gov/stream/). Select models are available for application to satellite imagery via our tutorials on GitHub (https://github.com/STREAM-RS). Overall, the range of supported sensors and products allows end users to leverage the sensor with the correct spatial, spectral, and temporal resolution for their given application in optically complex inland and coastal waters.
