JAXA Research and Development Report: Research Reports on High Altitude Balloons
A spectrometer has been developed that uses an acousto-optic tunable filter (AOTF) to measure minor constituents of troposphere and stratosphere by sun light absorption. The spectrometer consists of an AOTF, an RF generator to drive the AOTF and a photomultiplier to detect the light selected with AOTF. The weight of the instrument is 4.0 kg and power consumption is 7.0 W. A wavelength range to be scanned by spectrometer is 410 to 460 nm, and resolution of wavelength is 0.85 nm. A balloon (BT5-21) which accommodates the newly developed instrument was launched to measure NO2 at Sanriku Balloon Center on September 12, 2002. The results that was obtained successfully showed that height of NO2 maximum is 30 km and NO2 maximum density is 3.0 x 10(exp 9) cm(sup -3). The value agrees quite well with that obtained with UARS (Upper Atmospheric Research Satellite) 10 days after the balloon launch.
