Weight of the ozone layer 1 Incredibly, the ozone layer in the upper atmosphere that protects us from the ultraviolet rays of the Sun varies somewhat but, on the average, would be less than one centimeter thick if it were brought down to sea level. Given that the density of ozone at sea level would be about 2.0 grams per litre, what is the total amount of ozone (in Tonnes) in the upper atmosphere when its sea-level thickness is 0.22 cm? Take the radius of the Earth to be 6400 km. (The volume of a thin skin around an object is the surface area of the object times the skin thickness.)
