Ocean surface albedo (OSA) significantly influences air-sea heat exchanges and Earth's radiative balance, but accurately modeling it remains challenging due to high environmental variability. We propose a novel broadband parameterization integrating solar zenith angle and atmospheric transmittance, enabling seamless representation across clear-sky and overcast conditions. Coefficients were derived via nonlinear fitting to comprehensive observational data from the northern South China Sea. The parameterization demonstrates strong performance (R = 0.892, RMSE = 0.0132) and is independently validated using historical datasets from the North Atlantic and Central Pacific (R ≥ 0.75, RMSE ≤ 0.061). Residual analysis highlights secondary influences of wind speed, wave height, and humidity, indicating potential refinements. This physically interpretable and computationally efficient model is particularly suitable for climate simulations, radiative transfer studies, and remote sensing applications.
