Purpose of the flight and payload description

The objective of the ATMOSFER mission was to transport 12 experiments from different laboratories and universities. For the mission was used as platform CARMENCITA a multi-payload stabilized gondola originally introduced in late 2012 by the Nacelles Pointees (Pointed Platforms) CNES team, which was developed with several concepts in mind: modularity to allow the inclusion of several instruments devoted to the same or different research areas in one mission, reusability to overcome the difficult to adapt a platform specifically designed around an instrument to another (reducing costs and developing times), and finally cargo volume which is maximized to allow the installation of many instruments.

Onboard the gondola were installed the following instruments:

FIRMOS-B a Fourier transform spectrometer measuring the radiance emitted by the planet in the spectral band from 10-100µm in wavelength. It was developed at the Istituto Nazionale di Ottica (CNR-INO) from Italy, with funding from ESA and ASI. The instrument was built to support the FORUM satellite mission.

A ZEPHYR GONDOLA aimed to fly under the stratospheric pressurized balloons used by the Stratéole 2 project, being developed by the Laboratoire Atmosphères, Milieux, Observations Spatiales (LATMOS), the Laboratoire de Météorologie Dynamique (LMD) and the Division Technique of l'Institut National des Sciences de l'Univers (DT-INSU), in close collaboration with the CNES balloon sub-directorate. On board the gondola were the following instruments:

- ROC: GPS radio-occulation instrument
- LPC: particle counter
- B-BOP: ozone instrument
- VATA: sonic anemometer
- H2O TDLAS: laser hygrometer
