Summary Using atmospheric observations taken between 1901 and 1970, we have estimated the variations in atmospheric torques that excite the Earth's wobble. We have refined and brought up to date the time series of wobble excitation due to atmospheric mass redistribution that was obtained by Hassan over fifteen years ago, and have computed an entirely new time series of wobble excitation due to the mountain torques. A separate paper, (Wilson & Haubrich) compares the atmospheric series with a time series of the Earth's pole motion derived from astronomical observation.
