In April and May, increased wildfire activity was observed in Canada. Smoke from the fires was carried across the Atlantic Ocean to Europe. The Copernicus Atmosphere Monitoring Service (CAMS) has been closely monitoring the emissions from the fires and mapping the movement of the smoke and its impact on the atmosphere and air quality.

During fieldwork in South Pärnumaa, in the Nigula Nature Reserve, specialists from the Estonian Environment Agency noticed that very tall aspens—over 40 metres high—were growing there. To determine their exact location and height, a forest height map was used.
