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.
