Abstract:

An attempt has been made to draw quantitative conclusions from Tiros-I cloud pictures. Photometry made possible the construction of isopleths of brightness, and the computation of spectra of brightness variance. The spectra led to objective definitions of structure parameters, on the basis of which clouds can be classified into structured and nonstructured types. So far, the objective classification system does not agree entirely with subjective classification. Furthermore, sampling variations appear troublesome. Structured clouds are definitely of the cumulus type. Nonstructured clouds do not permit a clear-cut identification from Tiros-I pictures alone. Author
