Extract High Frequency Noise

How can I attenuate high frequency noise from airborne magnetic data, which are supposed microlevelled?
The fly lines are E-W and spaced ~500m

    David, looks like you have the GDB. In this case apply the non-linear filter to the mag data in the GDB. Adjust your filter width so that it just takes out the systematic noise without altering the nature of the real data, finally grid the filtered profile data.
