Land-Based Station

NCEI's land-based (in situ) datasets are developed from data collected across the United States and globally. Data availability varies by data type and station, and some have periods of record of more than a century. Any data product ordered from NCEI may be certified for court, but only the more commonly certified products can be certified for court online. For ordering certified copies of items where certifications are not offered online, please contact NCEI.
