Analysis of superconducting gravimeter data from Table Mountain, Colorado

SUMMARY We present an analysis of more than two years of data from the superconducting gravimeter CO24 at the National Oceanic and Atmospheric Administration’s Table Mountain Geodetic Observatory (TMGO) near Boulder, Colorado. The gravity data, sampled at intervals of 5 s, were cleaned for gaps, disturbances and oisets and then decimated to 1 hr, and an ETERNA analysis was done to determine the tidal gravimetric factors and phases, during which the atmospheric pressure loading and the period and damping of the free core nutation were obtained. We ¢nd T~418+14 days and 1152
