Final Flight / Science Report
Ozone in the stratosphere protects us from the Sun's harmful ultraviolet rays. However, ozone in the troposphere, closer to Earth’s surface, is a pollutant and hazardous to our health. UNF-UND team have successfully flown payloads on the NASA-HASP balloon flights since 2008 and measured the ozone gas profile in the stratosphere. Based on the success and experience of previous flights, the UNF-UND team proposes the HASP 2019 flight for the fabrication of new improved version of ozone sensors payload to measure bad ozone in the troposphere and good ozone profile in the stratosphere. In addition, we will explore the measurements of nocturnal ozone maxima before launching of the flight during early morning as well as in the troposphere after termination of flight at night time. The new nanocrystalline sensors will be fabricated and will be used for the payload, which will have better performance than previous flights. Three different types of nanocrystalline thin films ozone sensors boxes made by ITO, Ag2WO4 and WO3-x + ITO oxide semiconductor materials will be mounted on the three sides of rectangular payload body. Each sensor box will have 8 ozone gas sensors array. Ozone gas sensors will be fabricated and calibrated by the students’ team at UNF and will also be tested at UND. The UV light photodiode will be mounted just below ozone gas sensors box to measure amount of photovoltage generated by UV light, which will support the science concept of generation of ozone gas in the presence of UV light. This proposed HASP2019 flight science experiment will help us understanding good ozone in the stratosphere, bad ozone in the troposphere and any possible observation of higher concentration of ozone due to nocturnal ozone maxima after termination of flight at night time.
