Award Description: The overall goal of this project is to increase understanding of the conjugate nature of the polar ionospheres, which is in part a means to understanding the multi-scale global solar wind, magnetosphere, and ionosphere system. To accomplish this we intend on deploying 4 GPS receivers to AGO sites in Antarctica. These receivers will be capable of measuring total electron content (TEC) as well as phase and amplitude scintillation. These receivers will be used with several auxiliary instruments located in Antarctica to investigate the following science topics: 1. Investigate the formation and structuring of F-region ionospheric patches in the dayside cusp region, and their evolution as they are convected across the polar cap. 2. Investigate polar ionospheric upflow and outflow, and in particular the impact of polar cap patches on nightside dynamics and ionospheric outflow. 3. Estimate Pederson and Hall conductances, from the output of IDA4D throughout the southern high latitude region (see Figure 1 for an example conductances produced by IDA4D in the Arctic region), and investigate the relationships between the conductance, polar patches and MI coupling. 4. By simultaneously obtaining IDA4D maps of the Arctic polar region, we will investigate the conjugacy relationships between the two poles for the above three science topics. Anticipated results include several presentations on the research at scienctific conferences, and several papers in peer reviewed journals. Deliverables consist of quarterly and yearly reports, and a final report.
Project Description: Several initial telecons and email exchanges have taken place between the three main members of the scientific team: Dr. Murr, Dr. Ledvina and Dr. Bust. Dr. Bust and Dr. Ledvina had extended meetings while at the ION conference in Savannah (Sept. 22-25) and did on-site research as to the best GPS receivers and antennas to be purchased and deployed. A kickoff meeting between the three scientists will be held October 16-18. Dr. Bust has begun the process of developing a polar wind module, adding optical data to IDA4D and inquiring about getting test riometer data.
