Low frequency variations, Chandler and annual wobbles of polar motion asobserved over one century
Höpfner, Joachim (Scientific Technical Report / Geoforschungszentrum Potsdam; 2003, 01)Polar motion data is available from the mid-19th century to the present. Based on time series with a variety of sampling intervals (monthly, 0.05-year, 5-day and daily), we have separated the low-frequency terms by low-pass ... -
