For the past three years, the NCAR Archives has been building a digital archive of its holdings to provide access to its hidden collections, materials buried in the basement of NCAR's Mesa Laboratory that tell the story of atmospheric and Earth systems science. We have created online collection guides that are keyword searchable and supplemented by over 1,000 digitized items, offering those interested in the historical development and implications of weather and climate forecasts access to primary sources documenting this unique history anytime and anywhere. The historical development of forecasting science can be explored through the digital archive using materials drawn from the records of the Global Atmospheric Research Program (GARP), the GARP Atlantic Tropical Experiment (GATE), the Tropical Wind, Energy Conversion, and Reference Level Experiment (TWERLE), and NCAR's historic Atmospheric Technology Division. Digitized correspondence, status reports, newsletters, photographs, and design schematics of instrumentation, research aircraft, and scientific balloons offer scholars and the general public insight into the logistics of managing international field projects, scientific collaboration on an international level, breakthroughs in scientific data collection and instrumentation, and a variety of other themes. Weather and forecasting history is at the researcher's fingertips. Primary Contact: Kate Legg Archives and Digital Collections Librarian NCAR Library and Archives klegg@ucar.edu 303-497-8508 P.O.
