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2012年6月起在格陵兰冰盖SIGMA-A站点运行的自动气象站（Automatic Weather Station, AWS）所采集的时序数据。该自动气象站每小时采集一次气象观测参数，涵盖气温、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、雪面高度以及雪温。本数据集（数据级别：1.2）已通过简易数据掩膜处理流程，剔除了违背物理定律或观测环境下不可能存在的异常值。详细的数据级别定义与版本信息可参阅"readme_SIGMA-A_Level_1.2.txt"文件。强烈建议参阅自述文件中的"数据集修订记录"，并使用该数据集的最新版本。
