    • CDOM/fDOM and Landsat 8 Comparisons

    Metadata Updated: January 16, 2026

    This data set is combination of imagery from the Advanced Land Imager and Landsat 8 Surface reflectance data product covering three USGS gauge stations, Middle Haddam Connecticut (01193050), Potomac River at Little Falls (01646500), and the Susquehanna River at Darlington, Maryland (01579550) and the Sandy Hook to Jamaica Bays areas of the New York and New Jersey coast. Raw and corrected water quality data was collected from the NWIS database for the corresponding dates of Landsat 8 overpasses of all three sites. Calculations and functions from the Landsat bands were compared, such as band ratios and power functions were calculated and compared against the corrected data for Colored Dissolved Organic Matter.
