World Meteorological Organization (WMO) Resolution 40 NOAA Policy

NCDC data and products that contain international data may have conditions placed on their international commercial use.

The non-U.S. data cannot be redistributed for commercial purposes. For details, please consult the WMO policy.

The Online Store also provides service for our partner Data Centers—the National Oceanographic Data Center (NODC) and the the National Geophysical Data Center (NGDC)—and their products.

NCDC accepts Visa, MasterCard, American Express, Discover, wire transfers, and Automated Clearing House. Please refer to the NNDC Non-Federal Customer Payment Policy for additional information.

Check Order Status

Once you have received your order number, you can check the status of your order on the Check Order Status page.

Certified Data

Most states require records that are submitted as evidence in a court of law to be authenticated in some way. To accommodate this requirement, NCDC offers Department of Commerce certification of the data maintained in our archives. See the Certification of Data page for further information.

Consulting and Expert Testimony

NCDC is frequently called upon to supply professional meteorologists who can testify in court and render expert opinions regarding weather conditions at a given time and location. Providing expert opinions violates U.S. Government policy prohibiting competition with private enterprise, and Federal regulations do not allow it in almost all cases. Private-sector organizations that provide access to certified consulting meteorologists (CCM) include the American Meteorological Society (AMS), the National Council of Industrial Meteorologists (NCIM), and the National Weather Association. You may also consult your local telephone directory or visit the AMS CCM Finder.
