Sulphur dioxide over Klyuchevskaya Volcano measured by Sentinel-5A

Launched a little over three months ago, Copernicus Sentinel-5A has returned its first images – including a global map of ozone, maps of nitrogen dioxide over the Middle East and South Africa, formaldehyde over parts of Africa, and emissions of sulphur dioxide from an active volcano in Russia – showcasing the mission’s powerful capability to monitor atmospheric gases worldwide.

This image shows a plume of sulphur dioxide being emitted from the Klyuchevskaya Volcano in the Kamchatka Peninsula, far eastern Russia. It is one of the most active volcanoes in the world – having erupted more than 50 times since 1700 – is characterised by smoke continuously billowing above its summit.
