WATERHYPERNET: Dataset of in situ above-water hyperspectral autonomous optical radiometry measurements at the O1BE station

This dataset contains data from the WATERHYPERNET network at the O1BE station (Blue Accelerator Research Tower 1, Oostende, Belgium, 51.246°N and 2.919°E). WATERHYPERNET is a network of 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. WATERHYPERNET includes data from the PANTHYR (two TRIOS/RAMSES commercial off-the-shelf (COTS) hyperspectral radiometers mounted on a FLIR PTU-D48E COTS pan-and-tilt pointing system, Vansteenwegen et al., Remote Sens. 2019, 11(11), 1360) and HYPSTAR radiometers (i.e., lower cost hyperspectral radiometer mounted on autonomous pointing systems with embedded calibration devices developed in the frame of the H2020 HYPERNETS project with grant number 775983, www.hypernets.eu). Data are quality checked and accompanied with uncertainty estimates for the validation of all optical satellite missions.
