Ceilometer at Birkenes is detecting smoke from Canada

The Birkenes observatory in Agder is NILU’s oldest observatory; it has been in operation since 1971. It is one of the longest-running sites in Europe. Since August 2021, NILU is operating a Ceilometer at the site. It shows clouds and aerosols above the station. Below screenshots from 30 May – 15 June 2025, each for a full day and between ground and 8 km altitude. The first wildfire aerosols were seen on 31 May 2025, and after that during many days, see here the daily curtain plots for 11 and 14 June 2025. Note the red/orange signals are clouds – only the fainter blue colors are signs of aerosols.
