Pm. Mathews et al., LOVE NUMBERS FOR A ROTATING SPHEROIDAL EARTH - NEW DEFINITIONS AND NUMERICAL VALUES, Geophysical research letters, 22(5), 1995, pp. 579-582
For an oceanless, elastic, spheroidal, rotating and nutating Earth, we
present new definitions for the latitude-dependent Love numbers and g
ravimetric constant which are free of certain drawbacks of the definit
ions currently in use, and make the computation of quantities of obser
vational interest simpler and more direct. Numerical values, computed
for an Earth model characterised by ''modified PREM'' parameters, are
also presented. This model is designed to have the value estimated fro
m VLBI data for the eigenfrequency of the Nearly Diurnal Free Wobble (
NDFW), and assures thus an accurate representation of the NDFW resonan
ce in the Earth tides. To achieve current and future accuracy goals, t
he Love number values used must fully correspond to the definitions em
ployed-a requirement not consistently met in some existing programs fo
r analysis of space-geodetic data.
