INTERACTIVE TOOLS

We propose to the users interactive tools for selecting, drawing, analysing the Earth Orientation Parameters : EOP Parameters : selection / plots / numerical analysis Operational combined series C04 : 1962 - current week, 1 day sampling Long term combined series C01 : 1846-last year (with gaps), 0.05-year sampling Individual EOP series : selection, graphics, numerical analysis Look at the last evolution of the Earth orientation parameters : current year, 1 day sampling Comparison of the operational series Earth orientation matrix and derived parameters : Earth orientation matrix on line (with prediction) Time series of the Earth orientation matrix / precession-nutation matrix / instantaneous rotation vector Geophysical Excitation : Geodetic/Atmospheric/oceanic excitation functions of the polar motion and length of day : sampling 1day, fluctuations > 5 days Geodetic/Atmospheric and oceanic excitation of the nutation (Celestial atmospheric excitation functions) - fluctuations > 6 jours
