Impact of solid Earth tide models on GPS coordinate and tropospheric time series

Tregoning, Paul; Coleman, Richard; Watson, Christopher Stephen

Description

Unmodelled sub-daily periodic signals can propagate into time series of daily geodetic coordinates and tropospheric estimates at various different frequencies. Geophysical interpretations of geodetic products, particularly at seasonal timescales, can therefore be affected by poorly modelled signals in the geodetic analysis. In this study, we use two solid Earth tide models (IERS2003 and IERS1992) and analyses of global GPS data to demonstrate how this process occurs. Aliased annual and...[Show more]
