Firn Temperatures from NW Greenland

Firn temperatures taken in the NW sector of the Greenland Ice Sheet in 2013. Temperatures were collected at locations where similar data was first observed by Carl Benson in 1952-55 (see Research Report 70 of the Snow Ice and Permafrost Research Establishment (SIPRE), Benson, 1962). These data show the long term change in firn temperature caused both by warming of mean annual temperatures, and an increase in percolation intensity. Data is used and further discussed in: Polashenski, C., Courville, Z., Benson, C., Wagner, A., Chen, J., Wong, G., ... & Hall, D. (2014). Observations of pronounced Greenland ice sheet firn warming and implications for runoff production. Geophysical Research Letters, 41(12), 4238-4246.

2013年于格陵兰冰盖（Greenland Ice Sheet）西北片区采集的粒雪温度数据。本次采集的温度数据点位，与卡尔·本森（Carl Benson）在1952至1955年间首次观测到同类数据的点位一致（详见《冰雪与冻土研究机构（Snow Ice and Permafrost Research Establishment, SIPRE）第70号研究报告》，本森，1962年）。该数据集揭示了由年平均气温升高以及渗流强度增强共同驱动的粒雪温度长期变化特征。本数据集已被用于以下研究并得到进一步讨论：波拉申斯基（Polashenski, C.）、库尔维尔（Courville, Z.）、本森（Benson, C.）、瓦格纳（Wagner, A.）、陈（Chen, J.）、王（Wong, G.）等及霍尔（Hall, D.）（2014年），《格陵兰冰盖粒雪显著升温观测结果及其对径流产生的影响》，《地球物理研究通讯（Geophysical Research Letters）》，第41卷第12期，第4238-4246页。
