Single-particle elemental composition datasets and ice grain information of EPICA Dome C ice core

We present single-particle elemental composition datasets produced using a single-particle inductively coupled plasma time-of-flight mass spectrometer (sp-ICP-TOFMS) coupled to the Bern continous flow analysis (CFA) system on 10 climatic periods from the Antarctic EPICA Dome C ice core (EDC, 75°06′ S, 123°21′ E, 3233 m asl), ranging from 282 m to 3137 m depth. The single particle datasets consist of Elemental particle number concentrations (PNCs) for Si, Al, Fe, Ca, Na, K, Mg, and Mn, and super-micron dust PNCs measured using a laser sensor (Abakus) for 10 climatic periods, Anomalies in particulate-to-dissolved elemental mass ratios, normalized to the median mass ratios of shallow ice sections (<1100m), for 22 elements (Na, Mg, Al, K, Ca, V, Cr, Mn, Fe, As, Rb, Sr, Y, I, Ba, La, Ce, Pr, Nd, Pb, Th, and U) at 9-cm resolution, Atmoic amounts of Ca-Fe-Al codetected silicate paricles and K-Al or K-Fe codetected silicate and non-silicate particles for 10 climatic periods. In addiiton, supplemantary datasets for discussions include: EDC grain-boundary surface area estimated based on grain radius measurement (EPICA community members et al., 2004) with some assumptions (details described in Lee et al., preprint) Sample ages were determined by linear interpolation of the AICC2023 (Bouchet et al., 2023) to the center of each sampled interval, and sample temperature anomalies were estimated as interval means from the temperature record from Jouzel and Masson-Delmotte (2007).
