Observation and modeling of tsunami-generated gravity waves in the earth’s upper atmosphere

In the aftermath of the large Tohoku earthquake on 11 March 2011, a tsunami was launched across the Pacific Ocean. As the wave approached the islands of Hawaii, a wide-angle imaging system on the Haleakala Volcano operated by the University of Illinois in collaboration with Cornell University obtained the first-ever optical images of waves in the ionosphere/ thermosphere system […]

The Remote Equatorial Nighttime Observatory of Ionospheric Regions (RENOIR)

Introduction The Remote Equatorial Nighttime Observatory of Ionospheric Regions (RENOIR) project is a joint collaboration between researchers from several institutions, including The University of Illinois at Urbana-Champaign, Clemson University, Cornell University, the Brazilian National Institute for Space Research (INPE) and the Federal University at Campina Grande (UFCG). Through the construction and deployment of a RENOIR […]

Specification of Nighttime Ionospheric Irregularities: Occurrence, Spatial, and Dynamic Properties

In this project, we will develop automated analysis algorithms to extract pertinent spatio-temporal properties of ionospheric structures from an imaging database collected over the previous solar cycle. Effects on trans-ionospheric radiowave propagation will be studied using collocated radio (GPS) measurements. A database of structure occurrence, drift velocity, widths, and altitudes as a function of longitude, […]
