Source of Acquisition

Atmospheric Technology Division
Method of Acquisition This is a legacy collection; original box labels indicate the records came to the Archives from the Atmospheric Technology Division (ATD) Director's Office. Some materials came to the Archives in 2010-2011 as part of a project to clean up materials stored at an off-site storage facility.

Appraisal Information

Routine correspondence, meeting notices, personnel records, travel records, purchase orders, duplicate publications, reprints, and employment offers were weeded from the collection.

Accruals and Additions

Accrual of Research Aviation Bulletins and Aircraft Data System manuals in November 2013 from Janine Aquino, RAF (accession # 2013.023). No further accruals expected.

Processing Information

This collection was processed in winter of 2011. 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.
