ABSTRACT OPP-9725252 OPP-9725463 DIBB, JACK HONRATH, RICHARD UNIVERSITY OF NH MI TECHNOLOGICAL UNIVERSITY OPP-9727093 OPP-9727418 BLAKE, DONALD SHEPSON, PAUL UNIVERSITY CA-IRVINE PURDUE UNIVERSITY The project will determine the atmospheric concentration of nitrogen compounds in the atmosphere by conducting a field experiment at a field camp at the summit of the Greenland ice sheet. The concentration of nitrogen compounds in the atmosphere will be compared to their concentration in freshly deposited snow so that the record of atmospheric chemistry that is retained in the permanent ice record at the site may be interpreted for changes in the chemistry of the troposphere that have occurred since human activities began to affect the atmosphere. That record will lead to important conclusions about the human impacts of global change on the atmosphere and will allow an examination of the natural cycles of atmospheric chemistry over the past 100,000 years.

摘要 粤ICP备09000000号-1 DIBB，JACK 新罕布什尔州理查德大学 密歇根大学 OPP-9727093 CA-9727418 BLAKE，DONALD SHEPSON，保罗大学-欧文普度大学 该项目将通过在格陵兰冰盖顶端的一个野外营地进行实地实验，确定大气中氮化合物的浓度。 将把大气中氮化合物的浓度与新沉积的雪中的浓度进行比较，以便可以解释保存在该地点永久冰记录中的大气化学记录，以反映自人类活动开始影响大气以来对流层化学发生的变化。 这一记录将导致关于全球变化对大气层的人类影响的重要结论，并将使人们能够审查过去10万年来大气化学的自然循环。
