Evidence for long-lived polar vortex air in the mid-latitude summer stratosphere from in situ laser diode CH 4 and H 2 O measurements
International audience A balloon borne diode laser spectrometer was launched in southern France in June 2000 to yield in situ stratospheric CH 4 and H 2 O measurements. In the altitude region ranging from 20 km to 25 km, striking large spatial structures were observed in the vertical concentration p...
