Spatial decomposed concentrations of NO2 and PM2.5 air pollution in the United States at Census block group level
Description
This dataset includes the yearly block group level decomposed concentrations of four spatial components ("long-range", "mid-range", "neighborhood", "near-source") for PM2.5 and NO2, from year-2000 to year-2015. The concentrations are at the census block group level. The unit of concentrations is ug/m3 for PM2.5 and ppb for NO2. Block group is identified by variable "blockgroup_id"; the longitude and latitude of each block group centroid are indicated by "longitude" and "latitude". Names of concentration variables follow the pattern as "COMPONENT_YEAR". "COMPONENT" represents four spatial components; "YEAR" represents the last two digits of year-2000 to year-2015. For example, "long-range_00" represents the "long-range" component concentrations for the year-2000.
