A high-resolution IR spectrometer aboard the NASA Electra aircraft to measure the total column amount of SO2, O3, and HCl above the aircraft while flying over the Caribbean three weeks after the June 15 eruption of Mt. Pinatubo in the Philippines. South of 20 deg N latitude columns of SO2 were observed ranging from 2.0-3.7 x 10 exp 16 molecules/sq cm. In addition, the column amount of HCl averaged 1.5 x 10 exp 15 molecules/sq cm in the region of the plume. This represents a small increase in HCl above the amount, estimated from the previous measurements, that would have been presented had there been no volcanic eruption, but the increase is substantially less than that seen following the 1982 eruptions of El Chichon.
