- Researchers from UMSA's Laboratory of Atmospheric Physics launched stratospheric balloons to 30 kilometers above the Oruro Altiplano in a 12-day campaign beginning October 6, 2026, capturing a continuous vertical profile of greenhouse gases from near-stratospheric heights to ground level.
- Each balloon released an AirCore — a long coiled stainless-steel tube — that passively collects air samples at every altitude during parachute descent, measuring concentrations of CO₂, methane, and carbon monoxide across the full atmospheric column.
- Led by Bolivian doctoral researcher Laura Ticona in partnership with France's LSCE, this was the third time the campaign has been held south of Oruro, reinforcing Bolivia's role as a strategic site for global atmospheric science.
