    Abstract: A method for estimating noise in particle motion seismic recordings and upgoing (deghosted) and downgoing components of ecorded wavefields includes inputting pressure related and particle motion related seismic signals. A sparsity promoting transformation is applied to the input seismic signals. A matrix à and column vector {tilde over (b)} are constructed according to the expression: A ~ = ( I I 0 I - I ? ? I ) x ~ = ( d u n ) b ~ = ( A - 1 ? p A - 1 ? z ) , wherein d represents a down-going seismic wavefield, u represents an up-going seismic wavefield, n represents the noise and ? represents a user-chosen scalar to adjust emphasis of the noise.
