Observations of UVA, UVB, and UVC from a sounding balloon from ground to 100,000ft

Abstract

Currently there is lack in situ measurements of ultraviolet (UV) light in the stratosphere. Team TIGERS is a student team of six undergraduates from Louisiana State University (LSU) that are taking part in the Louisiana Aerospace Catalyst Experience for Students (LaACES) ballooning project funded by Louisiana Space Grant (LASPACE). Team TIGERS has designed a ballooning payload that measures the intensity within the UVA, UVB, and UVC bands. Originally the payload was designed to make measurements of the corona during the eclipses at an altitude of 80,000 ft, but the flight was unable to be flown due to weather conditions. However, a makeup flight will be scheduled for May 14. At the altitude of 100,000ft, it is possible to observe some of the shorter wavelengths emitted by the photosphere since the payload will be partially above the ozone layer. Once the payload is recovered, Team TIGERS will use the flight data to correct the intensity measurements for angles that are not normal to the sensor face. Then Team TIGERS will compare the intensity and wavelength throughout the duration of the flight. This flight will also help verify a UV measurement and orientation sensing systems that will be used on future flight that incorporate ozone sensors to allow for further study of correlation between stratospheric ozone and UV intensity.
