چکیده

We present evaluations of two-dimensional surface current fields based on quantitative comparisons of satellite images with numerical model results provided by the German Federal Maritime and Hydrographic Agency (BSH). Earlier studies have shown that multisensor data can be used to derive sea surface. However, a quantitative evaluation of the resulting vector fields is difficult, due to the low availability of in-situ measurements. Current predictions made by numerical models are of higher resolution, but still below the resolution of the computed currents. Additionally, they predict the currents for coarser water-depth intervals rather than the currents on the very surface. Thus, we explore different spatial interpolation methods and present the resulting comparisons.

From Multi-Sensor Tracking of Sea Surface Films to Mesoscale and Sub-Mesoscale Sea Surface Current Fields

The knowledge about mesoscale and sub-mesoscale sea surface current fields is of high interdisciplinary interest, since it results in a better understanding of ocean-atmosphere interactions. However, many available numerical model results are of resolutions, which are too coarse to investigate mesoscale and sub-mesoscale turbulent features like eddies, particularly in coastal waters. In this wo...

Gravity acceleration at the sea surface derived from satellite altimetry data using harmonic splines

Gravity acceleration data have grand pursuit for marine applications. Due to environmental effects, marine gravity observations always hold a high noise level. In this paper, we propose an approach to produce marine gravity data using satellite altimetry, high-resolution geopotential models and harmonic splines. On the one hand, harmonic spline functions have great capability for local gravity ...

Investigation of Geostrophic and Ekman Surface Current Using Satellite Altimetry Observations and Surface Wind in Persian Gulf and Oman Sea

The rise of satellite altimetry is a revolution in the ocean sciences. Due to its global coverage and its high resolution, altimetry classically outperforms in situ water level measurement. Ekman and geostrophic currents are large parts of the ocean’s current, playing a vital role in global climate variations. According to the classic oceanography, Ekman and geostrophic currents can be calculat...
