On the Introduction of Special Sensor Microwave Imager (SSM/I) Data into the Andes Acoustic Ambient Noise Model

Abstract

The Special Sensor Microwave Imager (SSM/I) provides nearly global data coverage relating to sea surface roughness once every 24 hours. A quadratic retrieval algorithm is developed that can retrieve foam coverage and root-mean- square (rms) wave slope statistics from the SSM/I data: I show how that roughness product can be interpreted as a sound source for ambient noise. The Ambient Noise Directional Estimation System (ANDES) is modified for demonstration purposes to accept the SSM/I data in the form of maps of rms wave slope. A crude transfer function, which relates wave slope to sound source intensity, is derived using historical sonobuoy ambient noise data. Presentation graphics software is developed that presents a computer console operator with a visual display of receiver location, transmission loss contours, and ANDES omnidirectional noise results overlaying the grey-scale map of rms wave slope used to force the model.
