AB: With the proliferation of satellite-based ionospheric measurement systems, opportunities exist for high-resolution ionospheric specification. These systems utilize optical and radio-based techniques. The optical techniques include, UV limb scanning, UV disk scanning, and UV disk imaging. The radio techniques include, radio occultations, radio beacon tomography, and radar altimetry. While assimilative models seek to routinely ingest these data and produce a global or regional specification of the ionosphere, coincident measurements from more than one technique provide frequent opportunities to directly reconstruct the ionospheric densities with a high spatial resolution. The concept is demonstrated by using coincident UV limb scan data from LORAAS with radar altimetry data from TOPEX. The limb scans provide vertical information and the altimetry data provides horizontal information. When combined a 2D reconstruction of the ionosphere is obtained over a large geographic region with high spatial resolution. Additional combination of existing satellites can be used to produce high-resolution ionospheric specifications. In the future, multiple sensors on the same satellite will routinely provide such opportunities. Examples of these satellites include COSMIC and NPOES.
