Spectral correction factors for the removal of glint perturbations in above-water radiometric measurements are theoretically computed for representative inland, coastal and open-ocean waters, accounting for spectral and atmospheric dependences. The simulation framework relies on the measurement protocol adopted by AERONET-OC and endorsed by the ocean color community to support the validation of satellite aquatic radiometric products. The theoretical computation of the correction factors, here termed <em>glint correction factors </em>or<em> </em> <em>-factors</em>, is performed in the 340–1020 nm spectral range by coupling <em>i.</em> a highly accurate plane-parallel scalar code to simulate the angular distribution of the spectral sky-radiance impinging at the water surface, with <em>ii.</em> a three-dimensional Monte Carlo code to model radiance reflections at a wind-roughened water surface. The impact of glint due to sky-radiance originating from the sun region (conventionally termed <em>sun-glint</em>) is separately discussed. Computed glint correction factors—for both the total sky radiance and its sole diffuse component—are available at Zenodo (<a href="https://doi.org/10.5281/zenodo.20609990" target="_blank" rel="noopener">https://doi.org/10.5281/zenodo.20609990</a>).
