中国第三极地区大气污染物（SO2，NOx，PM2.5）网格排放数据集（2019）

本数据集包含了中国第三极地区（西藏、新疆、云南、青海）的2019年二氧化硫、氮氧化物、PM2.5排放网格化清单。排放清单来源于清华大学王书肖教授课题组排放清单数据库，通过使用ArcGIS软件技术将排放清单处理为1km*1km的网格数据集。排放计算的基础数据基于公开数据搜集、卫星观测数据、文献搜集等方式，以排放因子法进行计算，数据来自于国家统计局数据及其它行业统计年鉴。该数据可用于模型工作者对于第三极区域气候及空气质量的进一步研究。

This dataset comprises a 2019 gridded emission inventory of sulfur dioxide (SO₂), nitrogen oxides (NOₓ), and PM2.5 for the Third Pole region of China, covering Xizang, Xinjiang, Yunnan, and Qinghai. The emission inventory is derived from the emission inventory database of the research group led by Professor Wang Shuxiao at Tsinghua University, and was processed into a 1km × 1km grid dataset using ArcGIS software. The basic data for emission calculation was collected via public data searches, satellite observations, literature reviews, and other approaches, with emissions calculated using the emission factor method, and the data is sourced from the National Bureau of Statistics and other industrial statistical yearbooks. This dataset is available for modelers to conduct further research on the climate and air quality in the Third Pole region.
