From: Shape and size constraints on dust optical properties from the Dome C ice core, Antarctica
(a) EPICA-Dome C stable isotope profile (Jouzel et al.38; black line) and dust flux records from Lambert et al.6 and Delmonte et al. 2008 (Coulter Counter in grey and Abacus in red); vertical blue lines mark the average position of the four set of samples (H1, H2, G1, G2) selected for this study from the old Dome C ice core. (b) Mode (triangles) and standard deviation (circles) of the optical thickness distributions from SPES data. The two values reported for sampleDC-617-4 (solid and open circle), are related to the presence of two populations (Fig. 1b). Ellipses evidence results obtained from samples discussed in Figs 1 and 2. Experimental errors are comparable to the size of the symbols.
