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.

#Strateole2 06_STR1 payloads shortly after their landing in Mali!
La semaine dernière un avion a parachuté ces deux appareils près du village de #Diguiciré à 40 km au nord-ouest de #Tenenkou, selon des sources locales des éléments de la Katiba Macina seraient venu l'incendié quelques heures après..... #Sahel
Believe it or not: #Strateole2 "grey" balloon celebrated today Jules Verne's novel by completing a stratospheric round-the-world journey in exactly 80 days!

We started monitoring data from the #Strateole2 balloons. Upper balloons designed to study the equatorial upper troposphere&lower stratosphere providing wind and temperature. Thanks: @NSF @INSU_CNRS @Scripps_Ocean @salcandido @CNES @strateole_2
50 RACHuTS profiles and counting! These are first of its kind profiles of temperature #TSEN, aerosol #ROPC, and water vapor #FLASHB 2 km through the #TTL. Lots of great data ratcheting in. Even early evidence of sub-visible cirrus clouds.
After 56 d + 19 hr of flight, a #Strateole2 balloon just performed the first circumnavigation around the Earth. @CNES long-duration balloons are truly unique to explore the lower stratosphere worldwide!

The 8th and last #Strateole2 long-duration balloon has been launched tonight from Seychelles. Thanks to all @CNES and science teams for this great campaign! Lots of achievements and lessons learned for next time.
@IPSL_outreach @latmos_ipsl @meteofrance @LASPatCU @Scripps_Ocean
And a second balloon the same night, with this time the @Scripps_Ocean ROC as well as @latmos_ipsl Boldair and Becool instruments. Thanks to @CNES team for this great #Strateole2 night!
@IPSL_outreach @NSF @meteofrance @INSU_CNRS @Strateole2USA
After 1 week of disruption due to the presence of tropical storm Belna in the vicinity of Seychelles, #Strateole2 launches have resumed. TTL2 balloon carrying @LASPatCU Floats and @INSU_CNRS pico-SDLA instruments is in the air!
