Strateole_2

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

[Louvel Stéphane @LouvelStephane]

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 !

@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 @strateole_2]

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

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

[Strateole_2 @strateole_2]

@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.

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 https://t.co/h8BUtag63R

Round-the-Earth #HungaTongaHungaHaapai infrasounds have been recorded by #Strateole2 balloons in the stratosphere several times on days following the eruption!

#Strateole2 balloon records of #HungaTongaHungaHaapai eruption on Jan. 15th. Impressive infrasound signals in the stratosphere!

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

[Strateole_2 @strateole_2]

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.

Green light for the 13th #Strateole2 flight tonight. Stars above us, convection approaching from the east.

+2 balloon flights tonight. 11 launched so far. And more to come! #Strateole2 continues.

Ongoing #Strateole2 balloon inflation!

[Strateole_2 @strateole_2]

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.

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

[Strateole_2 @strateole_2]

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
