| Outline of Final Research Achievements |
In order to understand stratosphere tropospphere enchange of aerosols over polar and subpolar region, aerosol observations by Balloon assisted Gliding UAV were performed at Syowa Station, Antarctica in January 2013 and 2015. Vertical profiles of aerosol size distribution and aerosol samples, up to 10km in 2013 and 23km in 2015, were obtained. Balloon soundings from Ice breaker, Shirase, for observation of aerosol and ozone concentrations also performed in 2014/15 austral summer in order to obtained meridional variation of aerosol and ozone profiles.
Based on the analyses of dataset of balloon borne aerosol sounding at Syowa Station from 1997, It was found that stratospheric aerosol over Antarctica has been increasing from 2000.
