NCAR Graphics and NCL Records

 Collection
Identifier: 04-00-NGRAP
Using computers to produce images as visual aids in understanding complex data has played an important role in atmospheric research since the early 1960s. Under different organizational structures since 1964, software developed within a single project at NCAR has undergone an unbroken evolution in making significant contributions in the area of computer graphics tailored to research in the atmospheric sciences. This collection documents that evolution.

The materials not only document specific advances but reflect the development of a branch of computer graphics in general. The project continues to thrive, indicated by the fact that there were 4,000 unique downloads of the software in 2010. This collection offer unique documentation of a project that has had a cohesive history and record of achievement for almost fifty years. Materials include correspondence, manuals, proposals, reports, photographs, and other files documenting various aspects of computing history.

Processing Information

This collection was processed over several months in 2010-2011. The archivist arranged the collection according to original order and rehoused the materials in acid-free folders, enclosures, and boxes. Fred Clare, a retired NCAR Graphics employee, added annotations to the finding aid at the folder level. Dick Valent, also a retired NCAR Graphics employee, assisted Mr. Clare in the identification of several photographs found in the collection.
