Preliminary results from SPIRALE balloon-borne in situ stratospheric measurements during 2009 polar summer
International audience The SPIRALE (french acronym for infrared absorption spectroscopy by tunable laser diodes) balloon-borne instrument has been launched twice within 17 days in the polar region (Kiruna, Sweden, 67.9°N - 21.1°E) during summer, at the beginning and at the end of august 2009. In sit...
