Magnetic disturbance is disturbance change of Earth magnetic field which occurs discontinuously during the occurrence of magnetic storm. It can happen at different stages of magnetic storm, Its range and shape are related to the scale and type of magnetic storm. The magnetic disturbance that occurs during magnetic storm of rather large-scale shows larger range and higher frequency and lasts longer period than that during magnetic storm of fairly small-scale.Researches show that the range of magnetic disturbance in practical work varies between several nanotesla to more than ten nanotesla, and the shape mainly exhibits linear gradient variation and nonlinear disturbance variation. These two typical kinds of magnetic disturbance both affect the result of magnetic survey, and can be eliminated through magnetic diurnal variation correction. In combination with practical work, this paper deals with the utilization of magnetic diurnal variation correction to eliminate magnetic disturbance.
