Seasonal Variations of the Earth's Gravitational Field: An Analysis of Atmospheric and Ocean Tidal Excitation

摘要

Laser ranging measurements to single satellite are sensitive to the Earth's gravitational field and its temporal variations. Using 13 years (1980-1992) of LAGEOS I laser ranging data, we have recovered monthly mean linear combinations of even and odd degree zonal spherical harmonic coefficients of the Earth's gravitational field.
