Abstract :
In recent years, satellite remote sensing has provided a global picture of westward-propagating Rossby waves. This paper reviews some techniques that are needed to extract the information about the waves from different satellite datasets. Geophysical effect corrections and signal processing techniques are described, including the use of the Radon transform on longitude/time plots of satellite data and its extension to the 3D domain. The main results in terms of global distribution and speed of Rossby waves are presented and discussed
