Description:
Results of the NASA-JSC UV photometer from flights on large balloons during the MAP/GLOBUS campaing of September 1983 are reported. Profiles obtained on September 14 and 24 agree within uncertainties above a height of 36 mb (about 22.5 km) indicating a degree of stability in the upper stratosphere. Measurements were made during ascent and descent of the first flight, and ascent of the second flight. Because the vertical descent rate of the first flight was five times lower than the ascent rate, more structure was obtained. Float altitudes of 32 km (8.1 mb) for the first flight and 39 km (3.1 mb) for the second flight were attained. Results from the photometer are compared with Nimbus 7 SBUV observations made at the same time. The profiles agree within 10 percent above the partial pressure peak. Above the ozone mixing ratio peak, the UV photometry values are about 1 ppmV lower for the second flight. The SBUV profile peak is 1-2 km higher in altitude than that of the UV photometer. Peak values agree within about 4 percent.
