Since the reflectors are favourable in the seismic records, and most of these records are impaired due to presence of noise particularly surface waves, therefore, applying the proper way to remove or weaken the noise with minimal damage to the reflectors in seismic data processing steps is important and undeniable. Attenuation of ground roll data with co-core trace transform method is the purpose of this article so that a two-dimensional image is converted into another one with the ρ and Ф parameters. In the following the co-core trace transform method was applied on the synthetic and real data in an area in southern Iran. This method is able to decrease the noise by reducing the amplitude and increasing the signalto noise ratio. The results were compared with F-K finally.
