Balloon-borne observation of Aitken nuclei in the Antarctic stratosphere and troposphere
The aerosol soundings were carried out at Syowa Station (69°00'S, 39°35'E), Antarctica in October 1983. The vertical distribution of concentrations of Aitken nuclei (particles larger than 0.002 μm in radii) up to 15km in height was obtained at 1600 LT October 17 by use of the sonde which c...
