Abstract:

One long-term goal of this research program is to develop an operational ionospheric electron density tomography processor with the following characteristics 1. Solve for electron density on a global grid and adapt the resolution of the grid based on the data coverage 2. Be capable of processing data over a long time period, with either regular or varying sample times based on data availability. 3. Accept multiple sources of data from both ground and space based sources 4. The output electron density can be directly ingested into ionospheric data assimilation models. 5. Be able to accept as input, ionospheric data assimilative model inputs to initialize the tomography inversion. 6. Be capable of running in near real-time in a completely automated manner The last year of research has resulted in an initial version of our tomography processor, ionospheric data assimilation 3D IDA3D, which has partially fulfilled the long-term goals stated above. A second long-term goal of this research has been to validate our tomography inversion algorithms in the field with real data and independent data from incoherent scatter radars ISR and ionosondes. Our work in the last year, as well as research conducted by other tomography investigators such as the research group from the University of Wales and from Northwest Research Associates has essentially demonstrated the validity of tomographic mapping of the ionosphere in mid-latitudes, low-latitudes and high-latitudes. We feel now, that this long-term goal has been met.
