  • Activity dependence of solar supergranular fractal dimension 
    Paniveni, U; Krishan, V; Singh, J; Srikanth, R (Blackwell Publishing, 2010-02)
    We study the complexity of supergranular cells using the intensity patterns obtained at the Kodaikanal Solar Observatory during the solar maximum. Our data consist of visually identified supergranular cells, from which a ...
