This dataset contains absolute radiometric observations of aquatic and celestial targets spanning a spectral range of 313 to 1640nm. Absolute radiometric observations were obtained using analog and digital instruments with similar hardware and processing. Observations at individual wavebands were obtained objectively and independently. Radiometric observations of the Moon and the Sun were obtained at Mauna Loa (HI) and Mount Laguna (CA), and radiometric observations of aquatic targets were obtained in the Southern Ocean, Mission Bay (CA), San Pablo Bay (CA), Grizzly Bay (CA), and Lake Tahoe (CA and NV). Additional verification (e.g., from satellite matchups, model results, or alternate processing methodologies) are included when appropriate. Additional methodological details are provided in the associated publication. ... : The datasets are summarized as follows: SolarPhotometry.csv contains solar Langley observations from Mauna Loa and Mount Laguna. Observations are the natural log of instrument flux and are presented as a function of air mass. Celestial radiometry was obtained using the Optical Sensors for Planetary Energy (OSPREy) instrument suite at Mauna Loa, and the newest compact generation of the instrument suite (C-OSPREy) at Mount Laguna. LunarPhotometry.csv contains Lunar Langley observations from Mauna Loa. Observations are the natural log of instrument flux and are presented as a function of air mass. Celestial radiometry was obtained using the OSPREy instrument suite. AquaticRadiometry-SO.csv contains observations (lowest to highest) of the normalized water-leaving radiance (Lwn; units: uW cm^-2 nm^-1 sr^-1) as a function of wavelength. Shipboard observations were obtained using a manually pointed radiometer, the Biospherical Surface Ocean Reflectance System (BioSORS), in the Southern Ocean under overcast sky ...
