WATERHYPERNET: Dataset of in situ above-water hyperspectral autonomous optical radiometry measurements

This dataset contains data from the WATERHYPERNET network. Hyperspectral above-water autonomous downwelling irradiance, downward (sky ) and upward (water) radiance and derived water-leaving radiance and reflectance acquired in the visible, near-infrared (and shortwave infrared) spectral range at different water sites with the PANTHYR (two TRIOS/RAMSES commercial off-the-shelf (COTS) hyperspectral radiometers mounted on a FLIR PTU-D48E COTS pan-and-tilt pointing system) and HYPPSTARR radiometers (i.e., lower cost hyperspectral radiometer mounted on autonomous pointing systems with embedded calibration devices developped in the frame of the H2020 HYPERNETS project with grant number 775983). Data are quality checked and accompagnied with uncertainty estimates for the validation of all optical satellite missions.
