It is shown that the snow stake measurements in central Antarctica systematically underestimate the value of the snow build-up. Two methods for the calculation of the corresponding correction to the snow stake measurements at Vostok station are developed to take this underestimation into account. The first method is based on the Sorge’s law to calculate the rate of compaction of snow layers using the vertical profile of snow density. The second method is based on the direct field measurements of this compaction. Two independent methods for the estimation of the snow accumulation rate in the vicinity of Vostok station are also considered: geodetic data on the rate of snow layer sinking and glaciological data from snow pits. The most reliable estimate of the snow accumulation rate in this region is 2.26 ± 0.10 g/cm² per year, that is 8 ± 4% higher than uncorrected values from snow accumulation measurements.

从桩号测量得出的南极中部（沃斯托克站）积雪率的低估

结果表明，南极中部的积雪量测量系统地低估了积雪的价值。考虑到这种低估，开发了两种计算对沃斯托克车站积雪量的相应校正的方法。第一种方法基于索尔格定律，使用雪密度的垂直剖面来计算雪层的压实率。第二种方法基于这种压实的直接现场测量。还考虑了两种独立的方法来估算Vostok站附近的积雪速率：关于大雪层下沉速率的大地数据和来自雪坑的冰川学数据。该区域积雪速率的最可靠估计是2.26±0.10 g / cm ² 每年比积雪测量的未校正值高8±4％。
