NASA launches new sensor to monitor changes in the ozone layer


Today’s Video of the Day comes thanks to NASA’s ScienceCasts series and features a look at the new sensor that NASA has recently launched to monitor long-term changes in the ozone layer.

The sensor, named SAGE III (Stratospheric Aerosol and Gas Experiment III), will be installed on the International Space Station this year. SAGE III will monitor the ozone layer at various locations around the Earth at all times of day and night by measuring the attenuation of sunlight as it passes through the Earth’s atmosphere. These measurements will allow scientists to determine the quantity and location of aerosols and gases in the ozone layer.

SAGE III will also be able to measure ozone levels in different layers of the atmosphere, including the Troposphere and Stratosphere.
