In the mid- to late-1960s, Dr. Barry hoped to train graduate students, but felt constrained by the UK’s limited research funding. In 1968, he accepted a post in the United States at the University of Colorado Boulder as an assistant professor at the Institute of Arctic and Alpine Research (INSTAAR). When the university assumed control of a World Data Center (WDC) for Glaciology in 1976, Dr. Barry became the center’s director.
The center started small, but grew quickly under Dr. Barry’s leadership. At first, the WDC consisted of a library, a glacier photo collection, and a small staff. In 1980, the WDC became part of the Cooperative Institute for Research in Environmental Sciences (CIRES), which is a partnership between the National Oceanic and Atmospheric Administration (NOAA) and the University of Colorado Boulder. In 1982, NOAA designated NSIDC as coexistent with the WDC, and the center adopted the NSIDC name.
In 1993, NSIDC became the location of a NASA Earth Observing System Data and Information System (EOSDIS) Distributed Active Archive Center (DAAC). NASA's NSIDC DAAC provides data and information on snow, sea ice, glaciers, ice sheets, ice shelves, frozen ground, soil moisture, cryosphere, and climate interactions, in support of research in global change detection, model validation, and water resource management.
Along with training and recruiting a dedicated staff at NSIDC, Dr. Barry also fostered international collaboration. Between 1986 and 2005, several Russian scientists visited NSIDC for extended stays and research, and Dr. Barry’s visits to Russia in the 1990s paved the way for multiple U.S./Russian data-rescue efforts. Meanwhile, one of Dr. Barry’s visits to China helped facilitate China’s establishment of its own WDC for Glaciology.
At NSIDC, Dr. Barry contributed to the Intergovernmental Panel on Climate Change (IPCC) assessments in 1990, 1995, and 2001. He served as a review editor for IPCC Working Groups 1 and 2 in 2007, an effort that contributed to the IPCC being awarded the 2007 Nobel Peace Prize.
Other honors for Dr. Barry include Lifetime Career Awards from the Climate and Mountain Specialty groups of the Association of American Geographers, a Fellowship from the American Geophysical Union, the Goldthwait Polar Medal from the Byrd Polar Research Center, the Founder’s Medal from London’s Royal Geographic Society, the Humboldt Prize from the Bavarian Academy of Sciences, a J.S. Guggenheim Memorial Fellowship, and designation as a Distinguished Professor of Geography by the University of Colorado Board of Regents.
