Summary

Hand-held hyperspectral spectroscopy data were collected in 2022 in Franks Tract, a flooded area located in the central Sacramento-San Joaquin Delta of California. The data were collected from a boat and co-located within pixels from the Ocean Land Color Imaging (OLCI) sensor on the Sentinel-3A and 3-B satellites. Data from 16 sites within 7 OLCI pixels were collected on three days: July 14, August 3, and November 3, 2022. Radiance measurements from the water, sky, and a reflectance plaque were collected to enable calculation of water-leaving radiance (Mobley 1999, Ruddick et al. 2019). At the location of each spectroscopy site, discrete water samples were also collected and analyzed for chlorophyll a, dissolved organic carbon, and [...]
