与其他大陆和陆地相比，南极洲严重缺乏对降水的现场观测。APRES3（南极降水，地面和空间遥感）是一个致力于从地面和空间改善南极降水观测的项目，以评估气候，评估和改进气象和气候模式。2015年11月至2016年2月，在南极洲阿德利海岸的Dumont d'Urville站部署了一项实地测量活动，使用x波段和k波段雷达、测雪仪、雪花相机和测差仪进行了密集观测，随后在2016年及以后进行了持续的雷达监测。在其他结果中，观测结果表明，很大一部分降水在到达并在表面积累之前在干燥的表面变热层中升华，这是剖面雷达测量得出的结果。虽然大部分数据分析和科学结果发表在专门的期刊上，但本文提供了对现在存档在pangea数据存储库（https://www.pangaea.de, https://doi.org/10.1594/PANGAEA.883562）中的数据集的简明描述，并向科学界开放，以进一步利用其用于南极气象和气候研究目的。
Compared to the other continents and lands, Antarctica suffers from a severe shortage of in situ observations of precipitation. APRES3 (Antarctic Precipitation, Remote Sensing from Surface and Space) is a program dedicated to improving the observation of Antarctic precipitation, both from the surface and from space, to assess climatologies and evaluate and ameliorate meteorological and climate models. A field measurement campaign was deployed at Dumont d'Urville station at the coast of Adelie Land in Antarctica, with an intensive observation period from November 2015 to February 2016 using X-band and K-band radars, a snow gauge, snowflake cameras and a disdrometer, followed by continuous radar monitoring through 2016 and beyond. Among other results, the observations show that a significant fraction of precipitation sublimates in a dry surface katabatic layer before it reaches and accumulates at the surface, a result derived from profiling radar measurements. While the bulk of the data analyses and scientific results are published in specialized journals, this paper provides a compact description of the dataset now archived in the PANGAEA data repository (https://www.pangaea.de, https://doi.org/10.1594/PANGAEA.883562) and made open to the scientific community to further its exploitation for Antarctic meteorology and climate research purposes.
