Abstract :
Analysis of atmospheric radio noise data collected during 20-24-h periods at Delhi, India, shows that the noise levels decrease linearly with sunspot number. This result may be useful in reducing prediction uncertainties. It also suggests that residual absorption in the nighttime is significant.
