Abstract

Detailed wet tropospheric fluctuation information will be required to support proposals to search for gravitational waves in ultra-precise Doppler data. In this article, similarities between the solar wind and tropospheric effects on apparent signal path length (“signal delay”) are used to hypothesize the following parametric model for low-frequency wet tropospheric path length fluctuation (with op w — RMS signal delay fluctuation, R,,, = total zenith signal delay, 0 ‘= elevation angle, and r, = averaging time): Op (R,,07,)=2X 107 RK. (sins "(r_/1000)°° Recent experimental observations of wet tropospheric signal delay fluctuations can be interpreted as confirming this parametric form. The model is used to suggest the appropriate conditions for collection of experimental tropospheric fluctuation data.
