- Аннотация: Processes of the solar-wind/magnetosphere interaction are commonly monitored by magnetic records on the ground. However, a serious drawback of the analysis of ground-based magnetograms is the inevitable variation of the magnetic response due to continual changes of the station location. An ideal, but impossible, solution of this difficulty that would help to discriminate temporal and spatial variations is the deployment of a “stationary” observatory with a fixed position in the solar-magnetospheric coordinate system. The desired result can be obtained with the proposed technique of “virtual magnetogram” (VM). This technique has been implemented for key magnetospheric domains (midnight auroral and dayside cusp regions) as an additional tool for monitoring the response of the geomagnetic field to solar wind and IMF forcing. VMs for a fixed reference system are reconstructed by 2D fitting and interpolation of 1-min data from world-wide distributed magnetic stations. A wide range of space physics studies, such as substorm physics, solar wind-ionosphere interaction, dayside-nightside coupling, sawtooth oscillations, etc. will benefit from the introduction of the VMs. The database of calculated VMs, as well as simultaneous interplanetary parameters and geomagnetic indices, are freely available via the site http://vm.gcras.ru/ for all interested researchers for testing and validation.
