The ozone layer is well known for its protective effect of life on earth's surface by screening the damaging solar UV radiation. It is therefore important to regularly monitor the amount of ozone around the globe. MeteoSwiss is regularily measuring the ozone present in the upper atmosphere above Switzerland with different instruments.

Atmospheric Ozone Monitoring
Total ozone amount above Arosa
The transparency of the atmosphere to the UV radiation from the sun is measured with spectrophotometers. From these measurements, the total amount of ozone contained in the column of atmosphere above the Arosa Observatory is calculated. In the figure to the left, the daily mean ozone is reported for the last 14 days.

Ozone profile above PayerneThe ozone profile is recorded using an ozone sonde attached to an aerological balloon. The ozone is measured in situ and the data are transmitted to the Payerne station during the ascent. Such profiles are measured three times per week on Monday, Wednesday and Friday noon. In the figure on the left, the last valid ozone profile is presented.
