At dawn, the research team released an ozonesonde to measure the vertical distribution of ozone and send the readings back by radio.

The night air carried an ozonelike tang after the lightning storm.

A sharp, ozoney tang lingered in the coastal air as the storm rolled in.

Ozonesondes were launched from the research vessel to collect detailed vertical profiles of ozone across the ocean.

The ozoneless storage facility preserved the delicate artifacts from further chemical degradation.

Some clinics offer ozonetherapy as an alternative to conventional treatments for chronic pain.
