In April 1979, measurements of nitrogen dioxide in the upper atmosphere were made near Soufriere volcano by twilight optical-absorption techniques. The derived value of 5 x 10/sup +15/ molecules per square centimeter column implies an enhancement of 25 percent over earlier abundances measured in the same latitudinal regions. This enchancement may represent the normal stratospheric variability of nitrogen dioxide in the equatorial region but in any case may be considered an upper limit to the volcano's effect on the total nitrogen dioxide abundance.
