In November and December of 2019 the Stratéole 2 team met in the Seychelles with plans launch 8 superpressure balloons and 5 scientific payloads. For all members of the Stratéole 2 team this campaign was aimed at testing our newly engineered instruments, flight command and environmental systems, and communications. The campaign more than met expectations with 8 successful launches and all instruments operational, with flights lasting more than 70 days. The team will apply the engineering and scientific lessons learned from this campaign to ensure successful science campaigns in 2021 and 2023.
Data from the Stratéole 2.0 campaign will be publicly available in late 2020. Some quick look profiles from the RACHuTS instrument are available.
