Global Station Coordinates and Earth Rotation Parameters from LAGEOS Laser Ranging distributed laser ranging stations and Earth Rotation Parameters were derived from LAGEOS laser range data. The computations are based on the orbit processor program UTOPIA developed at the University of Texas in Austin/USA and on an adjustment program system created at the Institut für Angewandte Geodäsie/F.R.G.BUOY 发表于 2025-3-27 09:18:41

A 30–60 Day Oscillation in Length-of-Day and Atmospheric Angular Momentum: Extratropical Origin?MC), and (ii) LOD variation from the JPL Kalman-filtered Earth-rotation series. We analyze the NMC records by latitude belts, in light of the UCLA GCM results, in order to identify possibly distinct sources of the AAM oscillation in the mid-latitudes and the tropics. Results suggest that two 30–60 dArbitrary 发表于 2025-3-27 14:20:09

Definition of a Terrestrial Reference Frame using IRIS VLBI Observations; Approaching Millimeter Accn can exceed 1 cm per year at some sites. Existing VLBI observing networks lack the global coverage necessary to realize the potential of the present accuracy levels. In the next few years much effort will need to be directed toward establishing observatories in under-represented portions of the glo生意行为 发表于 2025-3-27 22:06:22

Because water can be stored on land in many forms, including ground water, ice, vegetation, and soil moisture, the estimates of water storage effects are difficult to obtain, but the general order of magnitude can be inferred from共同生活 发表于 2025-3-28 03:16:39
