Gridded Data Files and Tools Data Utilities The grids are in HDF format. The grids can be viewed as layers by the Mapedit program.Mapedit A translator of an HDF grid to an ASCII table is available here. The ASCII table is suitable for import into ArcView.here Data Files The gridded emissions data files are here.here The gridded REMSAD data files are here.here The gridded PM2.5 data are here.here The gridded SO4 data are here.here
