St. Croix
T he Imaging Radar Interferometer on St. Croix is located close to the St. Croix campus of the University of the Virgin Islands. The instrument has the feature of looking perpendicular to B over the field of view of Arecibo.
During the summer of 2002, M. F. Larsen from Clemson University and D. L. Hysell from Cornell University used a portable radar to observe quasiperiodic (QP) echoes, showing that they arose from elongated, wavelike structures in sporadic E layers of the kind observed previously at Arecibo and tentatively associated with convection driven by neutral shear instabilities.
As a result of that campaign, an autonomous 30 MHz imaging radar interferometer has been installed as a joint project between Clemson University, Cornell University, and University of the Virgin Islands.
