Major Ion Concentration

The concentration of major ions (Ca2+, K+, Mg2+, Na+ and SO(4)2) from cloudwater and throughfall raw data samples collected on the summit of Mount Mansfield, VT. Please note that -555 = <0.005 and -55=<0.05.本数据集收录了采自美国佛蒙特州（VT）曼斯菲尔德山山顶的云水与穿透雨原始数据样本中的主要离子（Ca²+、K+、Mg²+、Na+及SO(4)²）浓度数据。请注意：-555代表数值小于0.005，-55代表数值小于0.05。
