On the Composition and Origin of Large and Giant Particles Observed at Syowa Station,Antarctica
P(論文) Large and giant aerosol particles were collected by means of a single-stage impactor at Syowa Station and their composition was examined with scanning electron and optical microscopes, X-ray diffraction and phase transition methods. Large and giant particles in the winter season were found to...
