(2027) Closing Mass-Consistent Earth Angular Momentum Budgets: Impact of Oceanic Excitation Uncertainty Contact : Lone Stumpe (stumpe@gfz.de), Robert Dill (dill@gfz.de) Affiliation : GFZ Helmholtz Centre for Geosciences, Potsdam, Germany, Section 1.3: Earth System Modelling Temporal domain : 15.01.2003, 00:00 UTC until 15.12.2003, 00:00 UTC Temporal resolution : monthly (GravIS epochs; GAM and AAM averaged over each epoch interval) Number of data records : 12 Subtracted mean values : mean of each component over total period of all yearly files Notes : These G-AHS data are constructed based on a set of consistently processed Earth rotation excitation functions and the geodetic angular momentum (GAM) derived from the 20 C04 series from the International Earth Rotation and Reference System Service (IERS) G-AHS = GAM - (AAM + HAM + SLAM). For the underlying excitation functions and the calculation of the GAM, see Stumpe et al.
