“…For example, our electric field distribution can be mapped to the magnetosphere and is therefore useful for tracing particles in the magnetosphere [21] . Joule heating from our calculations can be used as input for calculating neutral winds in the thermosphere, which will modify the original electric fields.…”

Reviewing briefly the recent progress in a joint program of specifying the polar ionosphere primarily on the basis of ground magnetometer data, this paper emphasizes the importance of processing data from around the world in real time for space weather predictions. The output parameters from the program include ionospheric electric fields and currents and field-aligned currents. These real-time records are essential for running computer simulations under realistic boundary conditions and thus for making numerical predictions of space weather efficient as reliable as possible. Data from individual ground magnetometers as well as from the solar wind are collected and are used as input for the KRM and AMIE magnetogram-inversion algorithms, through which the two-dimensional distribution of the ionospheric parameters is calculated. One of the goals of the program is to specify the solar-terrestrial environment in terms of ionospheric processes and to provide the scientific community with more than what geomagnetic activity indices and statistical models indicate.ionosphere, magnetogram inversion, ground magnetic data, space weather, solar-terrestrial environment

“…Once the ionospheric parameters are computed in this way, the output can be sent to institutions around the world where our output will become input for other modeling studies. For example, our electric field distribution can be mapped to the magnetosphere and is therefore useful for tracing particles in the magnetosphere: see Kamide et al (2000) for some preliminary studies. Joule heating from our calculations can be used as input for calculating neutral winds in the thermosphere, which will modify the original electric field.…”

We report the recent progress in our joint program of real-time mapping of ionospheric electric fields and currents and field-aligned currents through the Geospace Environment Data Analysis System (GEDAS) at the Solar-Terrestrial Environment Laboratory and similar computer systems in the world. Data from individual ground magnetometers as well as from the solar wind are collected by these systems and are used as input for the KRM and AMIE magnetogram-inversion algorithms, which calculate the two-dimensional distribution of the ionospheric parameters. One of the goals of this program is to specify the solar-terrestrial environment in terms of ionospheric processes, providing the scientific community with more than what geomagnetic activity indices and statistical models provide.
