The campaign was split into 3 phases:
-Week 1: March 21- 25 : Installation of most instruments, first rough tests on the 24th and 25th.
-Week 2: March 28 – April 1st : First week of experiments. The setpoints were discussed daily among participants to optimized the simulated conditions.
-Week 3 : April 4 – 8 : Blind week of experiment. Setpoints are defined by the referee board, following the participants wishes, kept unknown to the participants.
During week 2, the conditions were as follow:
| Date | Temperature (K) | Pressure (hPa) | Volume mixing ratio (ppmv) |

The lines with bold numbers correspond to conditions not used for scientific analysis. Only conditions characteristic to atmospheric conditions are considered, with the exception of low-ppm limits.
The experiments included 1h-long static conditions and dynamic transitions between static periods with pressurizing or pumping speed typical of balloon ascending or descending rate.
