CEDAR email: CEDAR Scintillation Workshop!

[Derr, Jason R Dr]

Hello upcoming CEDAR 2025 attendees!

We are inviting you to participate and submit short presentations to our CEDAR workshop "Ionospheric Scintillation and Plasma Density Irregularities: Impacts on Space Weather" (https://cedarscience.org/workshop/2025-workshop-ionospheric-scintillation-and-plasma-density-irregularities). The scope of the scintillation session has been expanded by comparison with last year, without the limitation of mid-to-low latitudes, and with an emphasis on space weather.  Our session will be occurring on Monday, June 10 at 13:30.  Below is a brief description of the session:

This session will focus on ionospheric scintillation in the presence of plasma density structures. Such plasma structuring is often enhanced during geomagnetically disturbed times (e.g., geomagnetic storms and auroral substorms), and causes increased scintillation compared to quiet times. Plasma density gradients set up by energetic particle precipitations, often from magnetotail activity, leads to both refractive and diffractive effects on radio waves propagating through the ionosphere from a GNSS satellite to a ground-based receiver. Here we aim to examine ionospheric plasma structure and stability in relation to GNSS phase and amplitude scintillation. Presentations on the development of plasma irregularities related to scintillation and the specific processes of diffractive and refractive scintillation are encouraged.

Please reach out to jason.derr at westpoint.edu if you are interested in delivering a presentation on your research at our session!

Sincerely,
