AB: Over the last many years, we have used a great deal of data to run data assimilation and 3D numerical models of the ionospheric electrodynamics, magnetospheric dynamics, and thermospheric dynamics. In order to create the best possible data assimilation inversions, and validate the models as well as possible, many different data types from many different sources need to be utilized. In this talk, we will describe the availability of such data and their general quality. We show how a large amount of ground-based magnetometer data have serious quality issues such as spikes, base-line shifts, saturation effects, and general noisiness. In addition, we will suggest possible ways in which the data quality and availability can be improved.
