| Abstract: | The main sources of nssSO24- and NO-3 were summarized in this paper. By analyzing the spatial distribution features of major ions in Antarctic ice sheet and studying on the different time of the same volcanic event recorded by different ice cores from different regions in Antarctica, this paper intends to study the transmission path of nssSO24- and NO-3. Results show that nssSO24- and NO-3 are transmitted to the ice sheet through long distance and high altitude. The procedure of the transmission is that nssSO24- and NO-2 are transmitted to the level between the top of troposphere and the bottom of stratosphere, then subsided to the ice sheet surface and spread to other regions. |
