HTAP_v2.2: a mosaic of regional and global emission grid maps for 2008 and 2010 to study hemispheric transport of air pollution

The HTAP_V2 dataset consists of 0.1degx0.1deg gridmaps (left bottom corner centered) of CH4, CO, SO2, NOx, NMVOC, NH3, PM10, PM2.5, BC and OC for the years 2008 and 2010. HTAP_V2 uses nationally reported emissions combined with regional scientific inventories in the format of sector-specific gridmaps. The gridmaps are complemented with EDGARv4.3 data for those regions where data are absent. The global gridmaps are a joint effort from US-EPA, the MICS-Asia group, EMEP/TNO, the REAS and the EDGAR group to serve in the first place the scientific community for hemispheric transport of air pollution.HTAP_V2数据集涵盖2008年与2010年的0.1°×0.1°网格地图（以左下角为中心点），包含甲烷（CH4）、一氧化碳（CO）、二氧化硫（SO2）、氮氧化物（NOₓ）、非甲烷挥发性有机化合物（NMVOC）、氨（NH3）、可吸入颗粒物（PM10）、细颗粒物（PM2.5）、黑碳（BC）与有机碳（OC）共10类大气成分数据。HTAP_V2数据集将各国上报的排放数据与区域科学排放清单相结合，以分部门专属网格地图的格式进行整合。针对数据缺失的区域，该网格地图将补充采用EDGARv4.3数据集的数据。这套全球网格地图由美国环境保护署（US-EPA）、MICS-Asia工作组、EMEP/TNO、REAS工作组以及EDGAR工作组联合研制，其首要服务对象为开展大气污染物半球传输研究的科研群体。
