SIGMA-AWS dataset

These automatic weather station (AWS) data were measured as part of the "Snow Impurity and Glacial Microbe effects on abrupt warming in the Arctic (SIGMA)" Project (link to http://www.mri-jma.go.jp/Dep/cl/cl6/sigma/sigma-e.html) supported by Japan Society for the Promotion of Science (JSPS), Grant-in-Aid for Scientific Research (S), number 23221004. The data set contain 1-hourly meteorological and snow parameters measured at sites of SIGMA-A and SIGMA-B on the northwest Greenland since summer 2012. SIGMA-A is located on the Greenland ice sheet and SIGMA-B on Qaanaaq ice cap. The measured parameters are air temperature, relative humidity, wind speed, wind direction, air pressure, snow height, downward and upward components of shortwave, near-infrared and longwave radiant flux densities, and snow temperatures. The measured data were received from the ARGOS satellite network in semi-real time every day. Photos of these AWSs are presented in SIGMA Project HP.本数据集的自动气象站（Automatic Weather Station, AWS）观测数据源自“北极降雪杂质与冰川微生物对气候突变增温的影响（Snow Impurity and Glacial Microbe effects on abrupt warming in the Arctic, SIGMA）”项目。该项目由日本学术振兴会（Japan Society for the Promotion of Science, JSPS）科学研究（S类）资助项目（编号：23221004）支持，项目链接为http://www.mri-jma.go.jp/Dep/cl/cl6/sigma/sigma-e.html。本数据集包含2012年夏季以来，在格陵兰西北部SIGMA-A与SIGMA-B两个观测站点采集的逐小时气象与积雪参数。其中SIGMA-A站点位于格陵兰冰盖之上，SIGMA-B站点位于卡纳克冰盖（Qaanaaq ice cap）。观测参数涵盖气温、相对湿度、风速、风向、气压、积雪深度、短波/近红外/长波辐射通量密度的下行与上行分量，以及积雪温度。观测数据每日通过阿尔戈斯卫星网络（ARGOS）以半实时方式接收。上述自动气象站的实拍照片可在SIGMA项目主页查看。
