The WINDY payloads were designed to investigate the stability of the post sunset equatorial F region ionosphere and the factors that predispose it to equatorial spread F (ESF), a spectacular phenomenon characterized by broadband plasma turbulence which degrades radio and radar signals at low magnetic latitudes. The goal of the investigation is to lay the foundation for a strategy to forecast this disruptive phenomenon. The Advanced Research Projects Agency (ARPA) Long-Range Tracking and Instrumentation Radar (ALTAIR) will be used in conjunction with other ground based instruments to monitor the state of the upper atmosphere/ionosphere and help determine if the scientific conditions are suitable for launch.

The Principal Investigator is Dr. Hysell, Cornell University.
