GISP2 temperature anomalies from δ40Ar fitting using Schwander et al. (1997) firn model and Goujon et al. (2003) firn model reconstructed using stabilized temperature from 70 to...

采用施万德等（Schwander et al., 1997）粒雪模型（firn model）与古容等（Goujon et al., 2003）粒雪模型，通过δ⁴⁰Ar（氩-40同位素偏差）拟合得到，且以70至……区间的稳定化温度为基础重建的格陵兰冰盖项目2号（GISP2）温度距平数据集。
