Strateole 2

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 second balloon of the #Strateole2 opening night, with this time the @latmos_ipsl nadir-pointing lidar to observe cloud tops, and the @Scripps_Ocean @gps_hammer GPS radio-occultation instrument to measure temperature profiles below the balloon. What a night!

Opening flight of the second #Strateole2 campaign! This balloon carries instruments that measure water vapor, aerosols, as well as temperature profiles down to 1.6 km below the flight altitude. Smooth launch in the Seychelles night.

#Strateole2 is back to Mahé international airport, Seychelles after two tough years of preparation in France and in the US. Thanks to Seychelles Meteorological Authority for their support. Weather is good. Expecting launches soon.

The @strateole_2 campaign uses @CNES superpressure balloons drifting around the globe to study the climate processes in the Tropical Tropopause Layer and the lower stratosphere, helping #Aeolus validation activities along the way🎈🛰️.

.@strateole_2 was also a validation campaign for #Aeolus data. There were an impressive 231 collocations between the balloons and Aeolus🛰️🎈. Basic meteorological measurements provided by the balloons will now be used to validate Aeolus data.

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

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
