Relationships Between Air and Snow Chemistry in Winter at Summit, Greenland

这项研究是六所大学研究人员之间的合作项目。 研究人员将通过增加冬季采样计划，将他们先前对格陵兰岛Summit冰川冰记录的大气化学浓度记录的研究从夏季研究扩展到全年。 来自格陵兰冰盖项目（GISP2）的冰芯记录已经被分析了大气化学的痕迹，但在获得完整的年度化学记录之前，无法对结果进行全面评估，因为冰芯结果中最大的信号是在冬季积累的雪。 直到今年，冬季采样计划在后勤上一直是不可能的。 一个完整的年度循环记录如何从GISP2冰芯现代大气记录在过去的11万年。

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.
