The research is a collaborative project among researchers at six universities. The researchers will extend their previous study of the record of atmospheric chemistry concentrations recorded I the glacial ice at Summit, Greenland form a summer-only study to a full year by adding a winter sampling program. The ice core record from the Greenland Ice Sheet Project (GISP2) has been analyzed for traces of atmospheric chemistry but the results cannot be fully assessed until a complete annual record of present chemistry is available because the largest signal in the ice core results form snow that accumulates during the winter months. A winter sampling program has been logistically impossible until this year. A complete annual cycle of the record of how modern atmospheric record from GISP2 ice cores for the past 110,000 years.

这项研究是六所大学的研究人员合作的项目。研究人员将通过增加冬季采样计划，将他们之前对格陵兰岛顶峰冰川记录的大气化学浓度记录的研究延长到全年，只在夏季进行研究。格陵兰冰盖项目(GISP2)的冰芯记录已经分析了大气化学的痕迹，但在获得目前化学的完整年度记录之前，无法对结果进行全面评估，因为冰芯结果中最大的信号来自冬季积累的雪。在今年之前，冬季采样计划在后勤上一直是不可能的。记录了过去11万年来现代大气如何从GISP2冰芯记录下来的完整的年度周期。
