Leipzig. The smoke from the extreme forest fires on the US West Coast in September 2020 travelled over many thousands of kilometres to Central Europe, where it continued to affect the atmosphere for days afterwards. A comparison of ground and satellite measurements now shows: The forest fire aerosol disturbed the free troposphere over Leipzig in Germany as never before.

BOREAL, Flying Far for Science
A fixed-wing UAV capable of extreme long-distance flights supplies essential research data to climate scientists and weather forecasters. The modular, accessible payload bay facilitates nearly unlimited sensor switch-outs to probe every aspect of the atmosphere.
After an inspiring meeting in 2014 with UAV designer Michel Gavart, Mistral Group CEO and BOREAL sister company M3 Systems President Marc Pollina bought the BOREAL drone outright. “I fell in love with it and also saw the possible synergies between our services and BOREAL. M3 Systems produces test measurement instruments, in particular for the automotive sector, and these tools can be used by the BOREAL drone.”
