Error Characteristics of Dynamic Topography Models Derived from Altimetry and GOCE Gravimetrylation length. Combining the MDT characteristics with the estimated geoid errors in the spectral domain resulted in a-posteori error estimates. In the two cases the MDT errors were improved from 20 cm to 6 cm and 5 cm respectively. For the geostrophic surface current components the errors were improved from 23 cm/s to 18 cm/s and 16 cm/s.jet-lag 发表于 2025-3-23 14:35:03

Satellite Altimetry: Multi-Mission Cross Calibration all satellites the error estimates for the radial component exhibit significant geographical pattern — even for TOPEX. The error components are also taken to calculate time series of relative range biases and geocentre offsets between all altimeter missions.事情 发表于 2025-3-24 00:37:34
An Experiment of Precise Gravity Measurements on Ice Sheet, Antarctica simulated the gravity measurements on the moving ice sheet by evaluating how well the gravity values of the second set (4 by 4 points) could be estimated from the gravity values of the first sets (5 by 5 points). The result suggests that the measurements with an appropriate data processing enable 10 μGal accuracy even on the moving ice sheet.兴奋过度 发表于 2025-3-24 03:55:57
Tide gauge monitoring using GPS+ 1.0 mm/year, and when corrected for the geoid rise, 1.6 + 1.0 mm/ year. Rates of recent years are even eight times higher. The possibility to detect minor changes in tide gauge benchmark height with GPS may be limited by GPS-related errors, which can be up to several mm even in a 10 km baseline.Banister 发表于 2025-3-24 10:19:02

Helmut Stache,Heinrich Großmann extends to other information such as documentation of datum information, metadata, exchange format, application classification, and levels of quality control. In relation to tsunami-enabled tide gauges, quality control is related to the availability of data in real-time and the use of automatic control and analysis procedures.helper-T-cells 发表于 2025-3-24 17:05:10
Helmut Stache,Heinrich Großmannere are presented results obtained with this campaign and some comparisons to past campaigns. The main objective is to check the stability of the GPS station in order to estimate vertical land movements and sea level variations. GPS results indicate a tendency of subsidence of 0.2mm/a with a standard deviation of 0.1mm/a at the station.袋鼠 发表于 2025-3-24 20:51:47

Regime Switching and the Wage-Price Spiralproduct is used where the gravity field is approximated by spherical harmonic coefficients up to degree and order 200. In the second case synthetic GOCE Level 1B data are used directly in a gravity field determination using least squares collocation. In case two the full spectrum geoid error was imp
