HamSCI @ AGU 2018

HamSCI @ AGU 2018

Tuesday, December 11, 2018 - 11:45

This week, many HamSCI members are presenting their research at the American Geophysical Union (AGU) Fall Meeting in Washington, D.C. The AGU Fall meeting is one of the largest geoscience meetings in the world, and consists of about 24,000 attendees. The scientific program includes sessions pertaining to all areas of geophysics, including space weather, the solar wind, auroral activity, the ionosphere, and the neutral atmosphere. Below is a list of selected presentations and sessions being given by HamSCI members, or of general interest to ham radio operators. The complete scientific program is available here.

Traveling Ionospheric Disturbances (TIDs)

Traveling ionospheric disturbances are space weather in nature and cause fluctuations in electron density that can have impacts on HF propagation.  Two techniques, GNSS based total electron content (integrated density through the ionosphere and plasmasphere), and incoherent scatter radar (direct altitude profiles of temperature, density, velocity), can provide spatial structure information on these disturbances.

Solar Flare and Storm Effects

Solar flares cause D region based HF blackouts, but have effects through the ionosphere and neutral atmosphere.  September 2017 was characterized by multiple solar flares as well as large geomagnetic storm perturbations.  Studying these helps understand the system's response to forcing.

Small-Scale Mid Latitude Irregularities

At mid-latitudes over North America, we have known for more than a decade that HF radars (SuperDARN) see almost constant backscatter from small-scale irregularities moving at slow ionospheric speeds.  The causes of these irregularities are still under investigation, but they are very useful as a remote diagnostic.  This will give updates on progress toward understanding the irregularity origins.  Their presence may cause short time period HF propagation path changes.
