On Wednesday, May 28, from 2:00 pm to 3:00 pm MT, NSF NCAR’s High Altitude Observatory (HAO) will host a seminar entitled "Ionospheric Sensing Using High-Rate GNSS Reflectometry and Occultation Measurements from Low Earth Orbit." The speaker will be Dr. Yang Wang, a visiting faculty member in the Ann and H. J. Smead Aerospace Engineering Sciences Department at the University of Colorado Boulder.

The seminar will explore a relatively new approach to ionospheric data gathering using GNSS receivers on low Earth orbit (LEO) satellites, offering wider coverage than ground-based systems. The presentation will focus on high-rate ionospheric total electron content (TEC) measurements from reflected signals and RO signals, discussing processing techniques along with their capabilities and limitations. Attendees will learn about the application of this data to improve TEC mapping, electron density assimilation, and the monitoring of ionospheric disturbances.
