We propose a method for decomposing a seismic record into atomic events defined by a smooth phase and a smooth amplitude. The method uses an iterative refinement-expansion tracking scheme to minimize the highly nonconvex objective function. We demonstrate the proposed method on a noisy synthetic record from the shallow Marmousi model. Finally, we show an application of our method to low frequency extrapolation on the same record. This note is a short version of Li and Demanet (2015).
