The volume mixing ratios of methane, acetylene, ethane, and propane were measured in the troposphere and stratosphere on April 5, 1984, at 33°N, over New Mexico, using the technique of grab sampling by evacuated spheres on a balloon platform. Following recovery, analysis was carried out in the laboratory. The evacuated sphere technique was also employed to obtain a tropospheric sample from Catherine Peak, New Mexico (2.86 km altitude). Tropospheric volume mixing ratios were CH 4 , 1.59 ppm; C 2 H 2 , 358 ppt (parts per trillion); C 2 H 6 , 365 ppt; and C 3 H 8 , 1440 ppt. In the stratosphere, acetylene was 60 ppt. For ethane and propane the mixing ratios at 11.6 km were 441 ppt and 84 ppt, respectively.
