Description
Summary:The system for the preparation of quasi-definitivedata of the INTERMAGNET standard is described. Unlike the final data, which was prepared no earlier than 1 year after the measurement, the data provided with the described system are available 1 day after the last series of absolute observations. Quasi-definitivedata are used to model fast variations in the main magnetic field of the Earth and to calculate indices of geomagnetic activity. The quality of the data obtained from a comparison of the approved final INTERMAGNET data and the data from the World Magnetic Model (WMM) and International Geomagnetic Reference Field (IGRF) model is analyzed. The quality of the quasi-definitive data obtained by the proposed method of automated algorithms is shown to be comparable to the quality provided by the traditional approaches to the preparation of the final INTERMAGNET standard data.
