Abstract

In satellite remote sensing observations, optical sensors and microwave sensors are often used. They can be used to validate next-generation coastal numerical models, or to set offshore boundary conditions for the numerical models, respectively. Meanwhile, high-frequency ocean radars provide coastal observations of surface currents with significantly high resolutions in both time and space. Hence, they can be further used to drive coastal numerical models, although such bays and straits in which ocean radars have been installed are quite limited in Japan. New missions and sensors, such as JAXA's new altimeter mission COMPIRA, are being planned, so that higher-resolution satellite observations can be expected in wide areas in the near future that can be used for coastal numerical models. It should be noted, however, that higher-resolution observations would significantly include various components such as tidal, wind-driven, and ageostrophic currents. These components are not well handled in the present numerical models, but they should be explicitly treated in the next-generation coastal models.
