The Upper Atmosphere


We are indebted to friends made during the deployment of our radar. These include colleages at INRA in Godet, The Université des Antilles et de la Guyane, Meteo France, and The Observatoire Volcanologique et Sismologique de Guadeloupe (OVSG - IPGP). This research is supported by the National Science Foundation.




T he Imaging Radar Interferometer on Guadeloupe is located on an agricultural research site operated by INRA of France. The radar has the feature of looking perpendicular to B at F-region altitudes over the field of view of Arecibo.

The radar is used to observe F region field-aligned plasma density irregularities associated with medium-scale traveling ionospheric disturbances in the ionosphere. Irregularities are also produced during geomagnetically active periods under spread F conditions. Aperture synthesis radar imaging allows us to observe the structuring and to compare it with observations made with the Arecibo incoherent scatter radar, resonace lidar , and Boston University imager .

The radar was deployed as part of a joint project involving Clemson University, Cornell University, and the University of the Virgin Islands. The first experimental results from summer campaigns in 2013 appear below.
