Availability of geomagnetic information

Abstract

The issue of public availability of the Earth’s magnetic field data is not adequately regulated. The paper presents a proposal to declare geomagnetic information publicly available only when its reliability drops to the reliability of the currently best publicly available global geomagnetic model. With such a criterion, the monitoring and prediction of the unreliability of the current geomagnetic information model GI2022 suggests a reliability period of the original geomagnetic information of at least three years from the epoch of reduction of the last geomagnetic network measurements.
The same should be the period of geomagnetic information public unavailability in Croatia. During this period it is necessary to pay adequate attention to the data safety.
