Accumulation measurements from stake farm Neumayer Pegelfeld Spuso, Ekström Ice Shelf, Antarctica, 2022@en

This publication series contains the accumulation measurements from stake farm Pegelfeld Spuso on the Ekström Ice Shelf, Antarctica. The stake farm at the Air Chemistry Observatory (Spuso), located approximately 1.5 km to the south of the present Neumayer Station, has been in operation since September 2009. It consists of 16 aluminum poles (balise), placed in a grid of 4 x 4 with a spacing of 10 m. Readings have been carried out in approx. weekly intervals by the overwintering staff of the air chemistry observatory. Each data set in the series contains all measurements of each stake from one calendar year in a tsv file, the average accumulation of the stake farm for each measurement and the standard deviation of the stake farm for each measurement. The data sets are accompanied by figures illustrating the development of the cumulative accumulation since the beginning of the measurements to date, a bar chart of the monthly accumulation for the year and a collection of panels (one panel per measurement) illustrating the variation of accumulation within the stake farm.本数据集系列收录了南极洲埃克斯特龙冰架（Ekström Ice Shelf）上佩格费尔德斯普索（Pegelfeld Spuso）测桩场的积雪积累量实测数据。该测桩场设于当前诺伊迈尔站（Neumayer Station）以南约1.5公里处的大气化学观测站（Air Chemistry Observatory，简称Spuso）内，自2009年9月起投入运行。测桩场由16根铝制测桩（balise）组成，以4×4的网格形式布设，桩间距为10米。大气化学观测站的越冬值守人员以约每周一次的频次开展读数测量工作。本系列中的每份数据集均以TSV文件格式存储某一自然年内每个测桩的全部实测数据，同时包含该测桩场每次测量的平均积雪积累量，以及对应测量的积雪积累量标准差。每份数据集均附带配套可视化图表：其一为自测量启动至今的累计积雪积累量变化曲线；其二为该自然年的月度积雪积累量柱状图；其三为一组面板图（每次测量对应一幅面板），用于展示测桩场内部的积雪积累量空间差异。
