A long-duration balloon project at the tropical tropopause to advance our understanding of climate processes

Atmosfer is the third and last flight of the @CNES balloon campaign. With 12 experiments on board, the balloon will fly during more than 11 hours in a small circle of 100 km around the @SSC_Rockets Esrange base.

3 novel #Strateole2 instruments are performing their maiden flight on this @CNES / CSA🎈 : BIS, X-Storm and VATA. @ISAE_officiel @IPSL_outreach @INSU_CNRS
CALASET gondola has been launched at 01:28 am Timmins local time with a balloon of 150,000 m3. Flight altitude will be 32.6 km before to begin a slow descent until 13 km. End of the flight tomorrow around 2:00 pm. @CNES @asc_csa

New preprint on Essoar: "Balloon-borne observations of acoustic-gravity waves from the 2022 Hunga Tonga eruption in the stratosphere" where we analyze volcanic infrasound recorded at 20 km altitude, thousands of kms away from the volcano essoar.org/doi/10.1002/essoa…

Round-the-Earth #HungaTongaHungaHaapai infrasounds have been recorded by #Strateole2 balloons in the stratosphere several times on days following the eruption! @CNES @INSU_CNRS @IPSL_outreach @ISAE_officiel @esa_aeolus

#Strateole2 balloon records of #HungaTongaHungaHaapai eruption on Jan. 15th. Impressive infrasound signals in the stratosphere! @CNES @INSU_CNRS @IPSL_outreach @ISAE_officiel @esa_aeolus

#Décryptage Un tour du monde pour observer le #climat 🌏? Les derniers ballons de la seconde campagne Stratéole-2 se sont envolés cette semaine. 🎈 On vous explique tout ici ⤵️ insu.cnrs.fr/fr/cnrsinfo/str… #lmd_ipsl
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. @IPSL_outreach @CNES @INSU_CNRS

Green light for the 13th #Strateole2 flight tonight. Stars above us, convection approaching from the east. @IPSL_outreach @latmos_ipsl @Scripps_Ocean @meteofrance

Yesterday night, we flew the 7th #Strateole2 balloon from Seychelles. @INSU_CNRS instruments onboard will measure greenhouse gases all across the tropics. The same day, Flight #2 had sadly to be terminated because of the loss of one com link in the gondola. @CNES @IPSL_outreach

The #Strateole2 campaign continues with the smooth launch (zero wind!) of its 6th long-duration balloon. This one carries the same instruments than the 1st (unfortunate) flight. We hope the best for flight #6. So far so good...! @INSU_CNRS @IPSL_outreach @CNES

The 5th #Strateole2 balloon is in the air tonight with @LASPatCU instruments: an aerosol counter and an aerosol/water vapor/temperature profiler. Lots of upcoming data to better understand water vapor transport through the tropopause. @IPSL_outreach @INSU_CNRS @Strateole2USA

Ups and downs last week: 4 launches in two consecutive days, yet one early flight termination. @CNES team promptly identified a specific issue with the balloon. Launches will soon resume. 👉 webstr2.ipsl.polytechnique.f… to follow #Strateole2 balloon tracks! @IPSL_outreach @INSU_CNRS

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. @CNES @IPSL_outreach @INSU_CNRS @LASPatCU

#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. @IPSL_outreach @CNES @INSU_CNRS @Strateole2USA

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🎈🛰️. Read more👉 earth.esa.int/eogateway/news…
