Presentation

Strateole-2 is a French-US project to study climate processes in the Tropical Tropopause Layer (TTL) and in the lower stratosphere. The project originality pertains to  the use of CNES superpressure balloons, capable of drifting for several months between 18 and 20 km altitude.

Strateole-2 will release a total of nearly 50 long-duration balloons in three separate campaigns between 2019 and 2024. Balloons are released from Mahé international airport, Seychelles, with the local support of Seychelles Meteorological Authority.

And this is the launch of the second #Strateole2 balloon in this beautiful Seychelles night. Both balloons will fly near 20 km of altitude for months (hopefully), surfing stratospheric waves around the Earth.
