Analysis of ionospheric electrodynamic parameters on mesoscales – a review of selected techniques using data from ground-based observation networks and satellites
We present a review of selected data-analysis methods that are frequently applied in studies of ionospheric electrodynamics and magnetosphere-ionosphere coupling using ground-based and space-based data sets. Our focus is on methods that are data driven (not simulations or statistical models) and...

| description |
We present a review of selected data-analysis methods that are frequently
applied in studies of ionospheric electrodynamics and
magnetosphere-ionosphere coupling using ground-based and space-based data
sets. Our focus is on methods that are data driven (not simulations or
statistical models) and can be used in mesoscale studies, where the analysis
area is typically some hundreds or thousands of km across. The selection of
reviewed methods is such that most combinations of measured input data
(electric field, conductances, magnetic field and currents) that occur in
practical applications are covered. The techniques are used to solve the
unmeasured parameters from Ohm's law and Maxwell's equations, possibly with
help of some simplifying assumptions. In addition to reviewing existing
data-analysis methods, we also briefly discuss possible extensions that may
be used for upcoming data sets. |
