摘      要：We study the complexity of the supergranular network through fractal dimension by using the Ca II K digitized data archive obtained from the Kodaikanal Solar *** data consist of 326 visually selected supergranular cells spread across the 23rd solar *** cells that were well-defined were chosen for the analysis and we discuss the potential selection effect thereof,mainly that it favors cells of a smaller size(20 Mm).Within this sample,we analyzed the fractal dimension of supergranules across the solar cycle and find that it is anticorrelated with the activity level.
