An Improvement of Parametrization of Short-Wave Radiation at the Sea Surface on the Basis of Direct Measurements in the Atlantic

M. P. Aleksandrova, S. K. Gulev, and A. V. Sinitsyn

Based on the data of recent high-accuracy measurements of the incoming fluxes of short-wave radiation in 2004–2006 in the Atlantic, errors of existing short-wave radiation parametrizations are estimated. It is shown that the largest errors occur under large cloud amount. A parametrization scheme is proposed that takes into account not only total cloudiness, but also morphological types of clouds. The scheme improves parametrization under large cloud amount.
