Quality-controlled datasets of Automatic Weather Station (AWS) at SIGMA-A site from 2012 to 2020: Level 1.3

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: 1.3) has been completed data masking procedures to eliminate all erroneous data records. Detailed information of the data level definition and versions are referred to "readme_SIGMA-A_Level_1.3.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站点部署的自动气象站（Automatic Weather Station，AWS）采集的时序观测数据。该自动气象站按小时间隔采集气象参数，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、雪面高度及雪温共10项观测指标。本数据集数据层级为1.3，已完成数据掩码（data masking）处理，以剔除所有异常数据记录。关于数据层级的定义与版本的详细信息，请参阅‘readme_SIGMA-A_Level_1.3.txt’文件。强烈建议参阅该说明文件中的‘数据集修订记录’章节，并使用本数据集的最新版本。
