AB: In this presentation, the results of the April 2002 world-day campaign are reviewed. Initiated by the Haystack Observatory, this campaign unites the efforts of eight incoherent scatter radars to collect ionospheric data during a major geomagnetic storm beginning on April 17, 2002. The participating ISRs are located along latitudinal and longitudinal sectors making this campaign unique and invaluable for studying spatial and temporal effects of ionospheric storms. Emphasis is given to describing pre-storm electron density depletions, storm-time ionospheric structure, and comparisons between the ISRs and TIMEGCM/ASPEN, a first principle physical model.
