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.
