AB: The US Naval Observatory Earth Orientation Department, as the IERS Rapid Service/Predictions Center, continues to make improvements to its combination and prediction program. One of the many improvements made in recent years was the inclusion of atmospheric angular momentum (aam) data in the prediction program. The addition of the aam data has increased the accuracy of our UT1-UTC predictions. This presentation will focus on a statistical analysis of the National Oceanic and Atmospheric Administration (NOAA) and the US Navy Operational Global Atmospheric Prediction System (NOGAPS) aam data provided, as well as provide a brief history of the incorporation and use of the aam data, and possible future improvements.
