Surface velocity monitoring by satellite altimetry and repeated ADCP observations

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

A method has been developed to monitor the surface velocity by combining satellite altimetry data and repeated acoustic Doppler current profiler (ADCP) observations. First, geostrophic velocity calculated from the altimetry data is compared with the ADCP observations, resulting in their good agreement after adjusting their spatial scales. Then, a set of observations of the temporal mean velocity is obtained by subtracting the altimetry velocity anomaly from the ADCP observations. Regularly sampled time series of surface velocity can be determined by adding the averaged mean velocity and the altimetry anomaly components, which describes variations of the Kuroshio and the Subtropical Countercurrent well.
