Global Atmospheric Research Programme Atlantic Tropical Experiment (GATE) Records

Identifier: 04-03-02-GATE

Scope and Contents

The GARP Atlantic Tropical Experiment (GATE) was a large and complex international scientific experiment designed to gain an increased understanding of the atmosphere and causes of climatic variation and change. GATE sought to learn how cloud clusters in the tropic transformed and redistributed energy within the atmosphere, knowledge that was needed for the development of numerical models for long-range weather prediction and for assessing the long-term effects of pollutants on the atmosphere. These materials focus primarily on NCAR's role in GATE, specifically aircraft flights and data management, but also include information about other aspects of the project. Materials include flight logs and debriefing forms, satellite imagery, correspondence, newsletters, workshop proceedings, mission reports, and photographs. Selections from the GATE Records have been digitized and are available in the NCAR Library's digital repository, OpenSky. The project webpage for GATE is also available:


  • 1972-1979
  • Majority of material found in 1974-1978

Processing Information

This collection was processed in fall 2010. Original order of materials in folders and folder titles were kept. The Archivist created Series and Sub-series to aid access to the materials. Preservation measures included removing sticky labels from folders and re-writing folder titles in pencil, buffering acidic sheets, removing some metal fasteners, flattening oversize documents, and re-housing the collection in acid-free folders and boxes. Records containing personal data and sensitive information, such as social security numbers and medical records, were shredded. Publications available in the NCAR Library were removed from the collection.
