Descripción
The Global Oscillation Network Group (GONG) project is planning to place
six observing stations around the world to observe the solar
oscillations as continuously as possible. This paper describes the
procedures that are being used to select the six sites. The latest
results of measurements of cloud cover obtained by networks of 6 (out of
10) radiometers show a duty cycle of over 93%, with the first diurnal
sidelobe in the window power spectrum suppressed by a factor of 400. The
results are in good agreement with the predictions of a computer model
of the expected cloud cover at individual sites.
