Ozone Monitoring Instrument (OMI)

The Ozone Monitoring Instrument (OMI) is a satellite-based sensor that tracks ozone levels in Earth's atmosphere. It measures how much ozone is present in the stratosphere (the ozone layer that protects us from UV rays) and monitors ozone pollution near the surface. OMI uses ultraviolet light to detect ozone concentrations and other air pollutants globally, providing valuable data for understanding environmental health, climate change, and air quality. By offering frequent and detailed observations, OMI helps scientists and policymakers make informed decisions to protect both the environment and public health.
