Strateole_2

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.

@LouvelStephane @CNES @asc_csa @TimminsSBB Bravo Mathieu !

Opening flight (COMICS) of the #STRATOSCIENCE @CNES balloon campaign in Timmins. Under a Zero Pressure Balloon of 150,000 m3, the gondola will be pointing to the sun during 6 hours at 32 km of altitude. @asc_csa @TimminsSBB

@stratoballoon Only VATA is developed by IPSL. BIS is developed by ISAE/SupAero, a aeronautics engineer school in Toulouse, France. And X-STORM is developed by LPC2E, Orleans, France. Thanks to you for keeping us updated of all balloon activities!

@strateole_2 Many thanks ! All were developed by IPSL?

3 novel #Strateole2 instruments are performing their maiden flight on this @CNES / CSA🎈 : BIS, X-Storm and VATA. @ISAE_officiel @IPSL_outreach @INSU_CNRS

@stratoballoon No, not yet. But hopefully soon :) BIS is detecting infrasound generated by earthquakes. X-STORM measures terrestrial gamma ray flashes emitted by thunderstorms. And VATA is a sonic anemometer.

@strateole_2 There are published details on them?

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/es…

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/st… #lmd_ipsl

Two more #Strateole2 balloon launches yesterday night! @IPSL_outreach @CNES @LASPatCU @Strateole2USA

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

+2 balloon flights tonight. 11 launched so far. And more to come! #Strateole2 continues. @IPSL_outreach @Strateole2USA @INSU_CNRS @CNES @LASPatCU

Ongoing #Strateole2 balloon inflation!

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
