#	Description: North GRIP Ice Core Last Glacial (120-10 KYrBP) nitrogen isotope (d15N) data and temperature reconstruction.
#	NGRIP d15N data measured at the Climate and Environmental Physics Division (KUP) of the Physics Institute at the University of Bern 
#	covering the period from the beginning of the Holocene to DO 8.  d15N data points represent 10 to 25 cm of ice, the depth corresponds 
#	to the TOP of the sample. The reconstruction is based on d15N data combined with a firn densification and heat diffusion model.

#	Abstract: In order to reconstruct the temperature of the North Greenland Ice Core Project (NGRIP) site, new measurements of d15N have been performed covering the time period from the beginning of the Holocene to Dansgaard-Oeschger (DO) event 8. Together with previously measured and mostly published d15N data, we present for the first time a NGRIP temperature reconstruction for the whole last glacial period from 10 to 120 kyr b2k (thousand years before 2000 AD) including every DO event based on d15N isotope measurements combined with a firn densification and heat diffusion model. The detected temperature rises at the onset of DO events range from 5 C (DO 25) up to 16.5 C (DO 11) with an uncertainty of +/- 3 C. To bring measured and modelled data into agreement, we had to reduce the accumulation rate given by the NGRIP ss09sea06bm timescale in some periods by 30 to 35%, especially during the last glacial maximum. A comparison between reconstructed temperature and d18Oice data confirms that the isotopic composition of the stadial was strongly influenced by seasonality. We evidence an anticorrelation between the variations of the d18Oice sensitivity to temperature (referred to as alpha) and obliquity in agreement with a simple Rayleigh distillation model. Finally, we suggest that alpha might be influenced by the Northern Hemisphere ice sheet volume.
