| Research Abstract |
The purpose of this research was the validation of our new instrument that can measure NO_2, OClO, and BrO with O_3. We prepared for the balloon experiment in 2010 but quitted due to the trouble of CPU in the instrument. We checked and improved the instrument in2011 and again prepared for the balloon experiment in 2012 but no balloon launched in this year due to the unusual meteorological condition. Therefore, test measurements were performed at ground on the sunrise and culmination. We confirmed that at least the stratospheric column of NO_2 can be derived.
