中国长三角区域大气细颗粒物PM2.5质量浓度空间分布数据集（2016）

本数据首先由长三角2016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：中国长三角区域大气PM2.5质量浓度空间分布数据集（2016）;(12个dat 格式文件)，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2016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 first developed by calculating monthly averages from hourly mean ground-level PM2.5, SO2, and O3 concentrations of prefecture-level cities released by the General Station of Environmental Monitoring under the Ministry of Environmental Protection for the Yangtze River Delta region in 2016, followed by interpolation using Kriging, also known as spatial local interpolation method.
The ground-level PM2.5 observations were conducted in accordance with the analytical methods specified in the National Ambient Air Quality Standard GB3095-2012. The measurement accuracy for PM2.5/PM10 is ±1.5 μg/m³ for hourly average mass concentration and ±0.5 μg/m³ for 24-hour average mass concentration, with a resolution of 0.01 μg/m³.
The dataset is named Spatial Distribution Dataset of Atmospheric PM2.5 Mass Concentration in the Yangtze River Delta Region (2016), which includes 12 files in DAT format. Here, PM2.5 indicates that the data element 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.
Each file contains the average PM2.5 concentration records at a 0.25-degree grid resolution for each month from January to December 2016.
