Quality-controlled datasets of Automatic Weather Station (AWS) at SIGMA-A site from 2012 to 2020: Level 1.2

Time-series data of an automatic weather station (AWS) operated at the SIGMA-A site on the Greenland ice sheet since June 2012. The AWS measures the meteorological parameters every hour, which are air temperature, relative humidity, wind speed, wind direction, atmospheric pressure, shortwave radiation, longwave radiation, near-infrared radiation, snow height, and snow temperature. This dataset (data level: 1.2) has been applied brief data masking procedures to eliminate anomalous values that violate physical laws or are impossible in the observed environment. Detailed information of the data level definition and versions are referred to "readme_SIGMA-A_Level_1.2.txt". It is strongly recommended to refer to "Dataset Revision Record" in the readme file and use the latest version of the dataset.

本数据集为部署于格陵兰冰盖SIGMA-A站点的自动气象站（Automatic Weather Station, AWS）自2012年6月起采集的时序观测数据。该AWS每小时采集一套气象参数，具体包括气温、相对湿度、风速、风向、大气压强、短波辐射、长波辐射、近红外辐射、雪面高度及雪温。本数据集（数据级别：1.2）已通过简易数据掩码流程处理，以剔除违背物理规律或观测环境下不可能存在的异常值。有关数据级别定义与版本的详细信息，请参阅"readme_SIGMA-A_Level_1.2.txt"文档。强烈建议参阅该自述文件中的"数据集修订记录"，并使用数据集的最新版本。
