1984-2009年中国大气本底站降水化学数据集

本数据集包含在中国气象局的瓦里关、上甸子、龙凤山和临安4个大气本底观测站的降水化学成分月平均统计数据。原始数据来自4个站的日常采样观测。在现场采集样品，分析pH和电导率，在中国气象局大气化学重点开放实验室分析主要离子成分。数据经过了一定的质量控制，然后处理成雨量加权的月平均结果。数据可用于环境科学、大气科学、生态科学、材料科学等相关学科的研究、管理和教学。

This dataset contains monthly average statistical data of precipitation chemical components from four national atmospheric background observation stations under the China Meteorological Administration (CMA): Waliguan, Shangdianzi, Longfengshan, and Lin'an. Raw data were obtained from daily sampling and observation at these four stations. Field samples were collected, with pH and electrical conductivity analyzed on-site, while major ionic components were analyzed at the Key Open Laboratory of Atmospheric Chemistry affiliated to the China Meteorological Administration. The collected data underwent necessary quality control processes before being processed into rainfall-weighted monthly average results. This dataset is applicable to research, management and teaching in related disciplines such as environmental science, atmospheric science, ecological science, materials science and other relevant fields.
