Stratospheric layer (5)

Ross

I believe the answer is:

ozone

'stratospheric layer' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for ozone that I've seen before include "Form of atmospheric oxygen" , "Sea air; toxic gas" , "Gas forming protective layer" , "Sea-air" , "By sea, you could take in this" .)

I've seen this clue in the Sydney Morning Herald, the USA Today, the Newsday.com and the Universal.
