In-situ trace-gas measurements from the ground to the stratosphere by an OF-CEAS balloon-borne instrument

Résumé

Monitoring climate change and stratospheric ozone budget requires accurate knowledge of the abundances of greenhouse gases and ozone depleting substances from the lower troposphere to the stratosphere. An infrared laser absorption spectrometer called SPECIES (acronym for SPECtromètre Infrarouge à lasErs in Situ) has been developed for balloon-borne trace gases measurements.The complete instrument has been validated on the occasion of a flight in August 2021 in the polar region (Kiruna, Sweden) within the frame of the "KLIMAT 2021" campaign managed by CNES for the "MAGIC" project using concomitant balloon and aircraft flights. Results of this flight concerning CH4 and CO2 will be presented.
