摘要：

The vertical emission profile of the O-2 (alpha(1) Delta(g)) airglow at 1.27 mu m has been measured during the evening twilight near the equator (Alcantara, Brazil; 2.5(0)S, 44.2(0)W) using a rocket-borne infrared photometer. The profile is used to derive the vertical distribution of ozone between 60 and 86 km. The ozone profile shows a minimum I concentration at 77 km and a secondary maximum of 1.34 x 10(8) cm(-3) at 82 km. The height of the secondary maximum is lower than observed at midlatitudes, and the 77-km minimum is sharper than that which has been observed at low latitudes by satellite measurements.
