1992-2009年中国降水年平均pH值和电导率分布图集

本数据集包含两类图：（1）中国气象局酸雨网观测的降水pH值年平均克里格空间插值图；（2）中国气象局酸雨网观测的降水电导率年平均值克里格空间插值图。原始数据来自中国气象局的酸雨站网观测结果。数据经过严格的审核，去除记录、录入和温度校正错误，还采用K-pH不等式法进行了质量控制和数据订正，少数无法订正的数据进行了剔除。采用SuperMap Deskpro 6软件，对站点观测的雨量加权年平均值进行克吕金插值，插值空间分辨率为0.12°×0.08°（经度×纬度）。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、管理及教学。

This dataset contains two types of maps: (1) Kriging spatial interpolation maps of annual average precipitation pH values observed by the China Meteorological Administration (CMA) Acid Rain Monitoring Network; (2) Kriging spatial interpolation maps of annual average precipitation electrical conductivity values observed by the CMA Acid Rain Monitoring Network. The original data are sourced from the observations of the CMA Acid Rain Station Network. The data have undergone strict quality review: errors in recording, data entry and temperature correction have been removed, and the K-pH inequality method has been adopted for quality control and data revision. A small number of data that cannot be revised have been eliminated. Using SuperMap Deskpro 6 software, Kriging interpolation was performed on the rainfall-weighted annual averages observed at the stations, with a spatial resolution of 0.12°×0.08° (longitude × latitude) for the interpolation. This dataset can be used for research, management and teaching in related disciplines such as environmental science, atmospheric science, ecological science and materials science.
