Magnetosphere: Real-time geomagnetic data acquisition from Siberia region and its application. PURAES project

Abstract

Monitoring and nowcasting of geomagnetic disturbance is necessary for conducting space weather forecast. As the energy from the magnetosphere flows into the ionosphere mainly concentrates on the polar region, it is important to watch the polar region. Developing geomagnetic observation points in the polar region and acquiring data in near real-time way are essentially effective for nowcasting and forecasting. Siberia is a missing region concerning near real-time data acquisition. PURAES Project (Project for Upgrading Russian AE Stations) has been conducted to upgrade magnetometer and set near real-time data transmission instrument in observatories in Siberia. In summer 2002, near real-time data acquisition from four observatories have been accomplished. AE index is the index which represents the geomagnetic activities in the polar region. Near real-time data acquisition contributes to that the AE index becomes better in its quality and quicker in its calculated output. Moreover, near real-time data is useful for various space weather forecasting application.
