中国京津冀区域大气细颗粒物PM2.5质量浓度空间分布数据集（2015）

本数据首先由京津冀2015年环保部环境监测站总站公布的各地级城市的地面PM2.5、SO2、O3小时均值计算月平均获得，然后通过克里格方法(Kriging)又称空间局部插值法进行插值计算得到。地面PM2.5观测观测参照国家《环境空气质量标准GB3095-2012》规定的分析方法PM2.5/ PM10精度：+/-1.5ug/m3(小时平均质量浓度),+/-0.5ug/m3(24小时平均质量浓度)，分辨率：分辨率：0.01ug/m3.数据文件名称编号：中国京津冀区域大气PM2.5质量浓度空间分布数据集（2015）;(12个dat 格式文件)，文件名中BHT为京津冀首字母缩写，PM2.5表示数据要素为PM2.5，Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec为1-12月份缩写。其中文件包含2015年1月-12月均值0.25度网格分辨率的 PM2.5的平均浓度记录数据This dataset is developed by first calculating monthly averages from hourly mean ground-level PM2.5, SO2 and O3 concentrations of prefecture-level cities published by the China National Environmental Monitoring Station under the Ministry of Environmental Protection in 2015, then performing spatial interpolation using the Kriging method, also referred to as spatial local interpolation. The ground-level PM2.5 observations comply with the analytical methods stipulated in China's Ambient Air Quality Standard GB3095-2012, with an accuracy of ±1.5 μg/m³ for hourly average mass concentration, ±0.5 μg/m³ for 24-hour average mass concentration, and a resolution of 0.01 μg/m³. The dataset is named *Spatial Distribution Dataset of Atmospheric PM2.5 Mass Concentration in the Beijing-Tianjin-Hebei Region (2015)*, which consists of 12 files in .dat format. The acronym BHT in the filenames stands for the Beijing-Tianjin-Hebei region, PM2.5 indicates that the data variable is PM2.5, and Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec are the standard abbreviations for the 12 months from January to December respectively. Each file stores the monthly average PM2.5 concentration records with a 0.25-degree grid resolution for the corresponding month in 2015.
