Past surface temperatures at the NorthGRIP drill site from the difference in firn diffusion of water isotopes

A new ice core paleothermometer is introduced based on the temperature dependent diffusion of the stable water isotopes in the firn. A new parameter called differential diffusion length is defined as the difference between the diffusion length of the two stable water isotopologues <sup&gt...
