The FAA requires aircraft-based in situ Eddy Dissipation Rate (EDR) observations to be delivered to the National Center for Atmospheric Research (NCAR) in Boulder, Colorado, and the ability to share this data with other United States (U.S.) governmental agencies, such as, but not limited to the National Weather Service (NWS). The data is used for the production of National Airspace System (NAS) aviation hazard advisory products issued by the NWS, and for product verification, evaluation, and as input into NCAR demonstrational/pseudo-operational turbulence product(s) delivered to various users in the global aviation community. In 2008, the International Civil Aviation Organization named EDR the official metric for reporting in situ turbulence. The World Meteorological Organization has also designated EDR as its official metric.
