✦ Synopsis

We have estimated the performance of several hypothetical ground-based networks intended to provide continuous observations of solar oscillations for one year. These networks were composed of from 2 to 6 stations distributed both in longitude and between the northern and southern hemispheres. Weather patterns at each site were simulated using a 4 parameter climate model and the results analyzed to yield the duty cycle of the representative networks.

The results indicate that a 2 station network might achieve a 60).o annual mean duty cycle, 3 stations might provide 75~ 4 stations might yield 822.o, and 6 stations might give a 93% annual mean duty cycle. Comparison of an existing 6 station network with our model of the same network suggests that the modelling procedure is realistic provided that the estimates of the climate parameters are accurate.

To illustrate the influence of such networks on observations of solar oscillations, we have created a synthetic time-line of solar velocities from published data and analyzed the power spectrum of the signal as 'observed' by various networks.
