Description
Remote sensing of the ionosphere using space-borne GPS instruments is a relatively new area undergoing rapid growth. This workshop is convened to discuss results from GPS-based measurements of the ionosphere and plasmasphere using receivers on multiple missions/constellations such as COSMIC, CHAMP, SAC-C, GRACE, C/NOFS, OCEANSAT-2, IOX, etc. We solicit reports on how these data are being used to address science questions and new discoveries. Also of interest are reports of how the data are being used in assimilative space weather models, new retrieval techniques, tomographic methods, and how the data are used in combination with other instruments and campaigns. We will encourage discussion and planning for future collaboration and joint efforts that take advantage of GPS-based measurements from space.
Speakers
Selected speakers are:
- Alan Burns, "The Summer Evening Anomaly and Conjugate Effects"
- Jann-Yenq (Tiger) Liu, "The ionospheric mid-latitude trough observed by FORMOSAT-3/COSMIC during solar minimum of February 2008 - January 2009"
- Nicholas Pedatella, "COSMIC TEC observations of longitudinal structures in the topside ionosphere"
- Chien Ya Wang, Semidiurnal and diurnal signatures in sporadic E occurrence rates derived from GPS-COSMIC Radio Occultation
- Paul Straus, "Radio Occultation Sensor Observations of Ionospheric Scintillation"
- Michael Nicolls, "Global E-region Densities Derived from Radio Occultation Measurements"
- Xinan Yue, Data Assimilation Retrieval of Electron Density Profiles from Radio Occultation Measurements
- Phil Stephens, "Statistical Analysis of COSMIC Derived Abel Profiles"
Workshop Summary
The presentations ranged from scientific applications to new techniques. Discussion suggests that community has made excellent progress in using these data, but more work can be done to improve upon their scientific and operational use. This includes developing techniques that are more accurate than the "baseline" Abel retrieval, including model-assisted assimilation techniques. Promising future directions are ionospheric structure studies and possible E-region studies after suitable correction of the Abel. The GAIM groups are planning to assimilate radio occultation data on a routine basis.
The COSMIC-Follow On constellation planned for first launch in 2014 ensures a robust future for radio occultation data from space.
