It is shown for the example of the analysis of the conditions of observation that the effect of the variability of the vertical and horizontal dimensions of the elements of a cloud field on the brightness of the cloud and cloud-free zenith must be taken into account separately. Estimates are obtained for the probability of the presence of a cloud along the line of sight from the results of photometric measurements (daytime).
