Integration of multiple satellite data for estimating sea surface transport

Abstract

A sea surface transport model integrating the non-divergent geostrophic surface transport model with an input of sea surface temperature and the wind impact model with an input of sea surface wind speeds has been developed to estimate the sea surface transport, south of Japan under the influence of winter monsoon. The estimated transport by the model is verified by the transport from the surface to the depth of 120 meters obtained from the data of a ship-board acoustic doppler current profiler(ADCP) and the geostrophic transport estimated from the dynamic calculation along the observation lines. Results indicate that the sum of the geostrophic transport obtained by the dynamic calculation and the wind-driven transport estimated by the model along the observation line accounts most of the observed transport from the ADCP data.
