Observation tools

Research of the atmosphere team is based on the use of instruments. Most of the instruments are developed in our laboratory.

Instruments in operation or under development:

  “SPECIES: SPECtromètre Infrarouge à lasErs in Situ”

Instrument on board an aircraft or a balloon for in-situ measurement by infrared laser spectrometry of trace gases from the free troposphere to the middle stratosphere.

“SAMU: Spectromètre de masse Atmosphérique  MUlti-espèces”

Chemical ionization mass spectrometer for in-situ ground and laboratory measurements of OH and RO2 radicals and H2SO4.

“Micro-Hygromètre”
Frost point hygrometer under development. This lightweight instrument can be installed under any type of atmospheric balloon to determine the vertical profile of the mixing ratio of water vapour and relative humidity. To date, its calibration bench has already been developed (see photo).
