The U.S. Naval Observatory is responsible for the determination and prediction of UT1-UTC. An investigation was begun to determine if atmospheric angular momentum (AAM) data could be useful in the National Earth Orientation Service (NEOS) combined solution and in the prediction of UT1-UTC. The investigation found AAM data to be useful possibly in the combined solution, but predictions of UT1-UTC were adversely affected when predictions of AAM data were introduced.
