Study of the Feasibility of Using Sea and Wind Information from the ERS-1 Satellite. Part 2. Use of Scatterometer and Altimeter Data in Wave Modeling and Assimilation

摘要

A third generation wave-model and a global wave assimilation system were used to study the sensitivity of waves to scatterometer winds, and to simulate real time use of ERS-1 altimeter data through assimilation of Seasat altimeter data. The assimilation of altimeter wave data demonstrates the potential of a coupled real-time wind/wave assimilation for quality assurance and validation of scatterometer and altimeter data. The two-dimensional wave spectrum from a third-generation wave model can be used in interpretation and validation of the synthetic aperture radar image spectrum.
