Abstract
“How far can I see to-day?” This question “assumes in the minds of the aviator and navigator an importance greater, perhaps, than that of any other meteorological matter. For such men it takes the place of that great public question which Sir Napier Shaw has called the fundamental problem of meteorology—‘Will it rain to-morrow?’” Thus far the author who, in his introductory chapter, remarks very pertinently that the term visibility was not well chosen, the visibility of an object being an expression of the ease with which it can be seen, whereas “visibility” is a distance, and moreover, is the distance at which an object cannot be seen.
