| contents | Holocene temperature anomalies (0.07...11.5 kyr b2k) of Greenland Summit were reconstructed from firn model inversions of GISP2 d15N, d40Ar and d15Nexcess data. Three different accumulation rate datasets for the GISP2 site and two different firn densification and heat and gas diffusion models (Schwander et al., 1997; Goujon et al., 2003) were used for uncertainty estimation. The GISP2 accumulation data used (0.02...35 kyr b2k, original data from: Cuffey and Clow, 1997), based on the GICC05 chronology (Rasmussen et al., 2014; Seierstad et al., 2014), are published together with the temperature anomalies. The file contains the most robust temperature estimate (T(d15N)) together with modelled firn parameters (delta age, lock-in depth, firn temperature gradient), modelled isotopes (d15N, d40Ar and d15Nexcess) on gas and glacial scales for all isotopic inversions (d15N, d40Ar, d15Nexcess) together with the respective reconstructed temperature anomalies. All data are synchronised with the GICC05 chronology. For details see: Döring and Leuenberger, 2022.
