Abstract:
The results of measurements of the total cloudiness using two ground instrumental methods are presented. The first method is based on an analysis of the blue sky and the second method uses a two-dimensional wavelet analysis. According to studies, measurements with the both methods fit together well, but differ greatly from traditional visual data, especially in the presence of cirrus clouds in the sky. Both methods use simple algorithms and low-cost recording devices. This allows applying them for remote measurements of total cloudiness automatically without human presence.
