Since 1987, ICAMS and its predecessors have been the custodian of the Federal Meteorological Handbooks. The Handbooks define meteorological data and metadata standards and guide data management practices across all Federal agencies, ensuring meteorological data is managed efficiently and effectively. Standardized data management practices, exercised by all partners in the Federal Meteorological Enterprise, lead to improved data quality and reduced costs.

All Federal Meteorological Handbooks, including changes, are linked on this page.
