In Memoriam: Patricia Doherty

Patricia Helen Doherty, Boston College, passed away Thursday, July 14, at age 72. Patricia was employed by Boston College for many years, serving as the Director of the Institute for Scientific Research at the time of her passing. Her research included studies of space physics, space weather, ionospheric and atmospheric effects on space-based systems with an emphasis on GNSS, ionospheric measurement techniques, chemical reactions in space, and magnetospheric physics. Pat Doherty has made pioneering and sustainable contributions to advance our understanding of ionospheric effects on satellite navigation. She was involved in the early assessment of ionospheric delay impact on GPS measurement errors. She played an important role in evaluating ionospheric limitation of FAA’s Wide Area Differential GPS (WADGPS) and performances of algorithms to correct ionospheric errors for WASS. During the past two decades, she and her collaborators have studied the ionospheric impact on GNSS at every continent and every region of the world.  In recent years, she has focused her attention on the broader field of space weather phenomena and its impact on technology and society.
