“…Colored triangles depict the locations of glaciological boreholes or snow pits; their color represents the inferred surface accumulation rates according to Ekaykin et al . [] in the same color scale as the inverted marker velocities. The star represents Vostok station in the color corresponding to the accumulation rate determined there.…”

“…Indeed, the general increase in the downward particle velocity from S to N is consistent with the increase in surface accumulation rate revealed by shallow cores and snow pits [ Ekaykin et al . []; colored triangles in Figure ]. Furthermore, the increased particle velocities along the W shore compared to the lake axis correspond with the notion of a local anomaly of increased accumulation along the shoreline related to the concave surface curvature [ Ekaykin et al ., ].…”

“…5). The winter maximum is attributed to clear-sky precipitation, the summer ablation, as well as the increase in moisture transport resulting from the winter weather systems (Bromwich 1988;Ekaykin 2003). However, the performance of the moisture-related atmospheric physics in ERA-Interim may be poor under cold conditions, and result in small snowfall in winter.…”

“…Sufficiently long-time series of accumulation observations (at least 5-10 yr) are a prerequisite for the determination of seasonal cycle of snow accumulation over Antarctica (Schlosser 1999;Jouzel et al 2003 (Lazzara et al 2012). Corrected gauge measurements of precipitation at Vostok are used due to its agreement with accumulation from a stake network at Vostok station (Ekaykin et al 2004). Figure 5 shows the averaged seasonal distribution of SMB or precipitation from in situ observations and the climate models (ERA-Interim, JRA-55, MERRA, RACMO2.1, and RACMO2.3) for the respective observation periods.…”
