Meteorological Observations at Schiaparelli Glacier Automatic Weather Station (AWSglacier), Cordillera Darwin, Chile, 2013-2019

The publication series contains meteorological measurements from an automatic weather station installed on the glacier surface (140 m a.s.l. in September 2015) of Schiaparelli Glacier, Cordillera Darwin, Chile. The station has been installed by the Universidade Federal do Rio Grande, Brazil, in August 2013. The station fell into a crevasse in February 2015 and was reinstalled in September 2015. It measures 2m air temperature (T), relative humidity (RH), global radiation (G), air pressure (Pres), wind speed (U) and wind direction (Dir) in an hourly interval (hourly averaged). The data provided here has been corrected for outliers, radiative heating of the temperature sensor and sensor freezing. After the reinstallation in September 2015, an issue with the relative humidity measurements has been found. Relative humidity has been corrected using specific humidity from a nearby station (AWSrock) and air temperature, and included in the dataset as well (RHcorr).本数据集系列包含智利达尔文山脉斯基亚帕雷利冰川表面自动气象站（automatic weather station）的气象观测数据，该站点2015年9月重新布设时所处海拔为140米（above sea level, a.s.l.）。该自动气象站由巴西里约格兰德联邦大学（Universidade Federal do Rio Grande）于2013年8月布设，曾于2015年2月坠入冰裂缝（crevasse），并于2015年9月完成重新布设。该站点以小时为间隔输出小时均值数据，采集参数包括2米高度处的气温（air temperature, T）、相对湿度（relative humidity, RH）、总辐射（global radiation, G）、气压（air pressure, Pres）、风速（wind speed, U）及风向（wind direction, Dir）。本次发布的数据集已针对异常值（outliers）、温度传感器的辐射加热效应及传感器结冰（sensor freezing）问题完成校正。2015年9月重新布设后，相对湿度观测出现异常，研究人员借助邻近站点AWSrock的比湿（specific humidity）数据与气温对相对湿度进行了校正，校正后的相对湿度（RHcorr）亦已纳入本数据集。
