Atmospheric oxygen layer (5)

Ross

I believe the answer is:

ozone

(Other definitions for ozone that I've seen before include "Sea air; toxic gas" , "Gas; bracing sea air" , "Sea air (found in layer?)" , "Layer that protects against ultraviolet rays" , "Seaside air, maybe" .)

I've seen this clue in the Newsday.
