| Abstract: | A first ISRO-DFVLR collaborative balloon flight of the MPAE cryogenic sampler was conducted at Hyderabad, India (17.5°N), on March 27 1985, and 15 air samples were collected between 10 and 35 km altitude. Vertical profiles of source gases analysed from these samples, such as CCl3F, CCl2F2, CBrClF2, and CH4 are presented. Due to tropical upwelling, mixing ratios of source gases decrease less rapidly with altitude than at mid-latitudes. |
