Abstract
Purpose. The International Geophysical Calendar designates selected days and intervals for special attention for geophysical experiments and analysis and is thus a framework for worldwide coordination. The calendar serves mainly the branches of geophysics dealing with the earth's atmosphere in which many phenomena vary significantly during the course of a year. In some experiments, such as the routine recording of variations of the earth's magnetic field, the observing and analysis programs at observatories are normally carried out at a uniform level throughout the year; in these cases the calendar is not needed.
