The National Scientific Balloon Facility (NSBF) Records document the early days of the NSBF while it was managed by National Center for Atmospheric Research (NCAR). Records illuminate the logistics of conducting balloon flights abroad and at home, particularly during the Cold War era. The collection offers a window into instrumentation, modifications, and issues with balloons and electronics packages. The collection includes correspondence, memos, budgets, reports, proposals, and papers. Selections from this collection are available online.
