Synoptic Comparison of Salt Marsh Spatial Structure Using Hyperspectral Imagery at NOAA National Estuarine Research Reserves.
As a dynamic system, salt marshes are highly productive habitats. Exceedingly dependent on specific tolerances to tidal regimes, temperature, elevation, and salinity, the plant composition and structure of a salt marsh are highly variable. Due in part to their visible spatial patterns and the …

Deep learning for downscaling GOES-18 measurements for wildfire detection
… low Earth orbit (LEO) satellites like Suomi-NPP, NOAA-20, and NOAA-21 with the Visible Infrared Imaging Radiometer Suite (VIIRS) imager provide high spatial resolution but with limited temporal coverage. To overcome these limitations, this research proposes a deep learning framework for wildfire …
