Diesel Pollution Indicator: Railyards
The DPI shows High and Medium DPI observed on roads adjacent to the group of railyards, which are located in the northwest section of West Commerce, the largest ones being the neighboring BNSF and Union Pacific railyards. Road segments with higher DPI near railyards may be caused by trains, trucks, and other diesel equipment. Aclima’s DPI shows that diesel emissions can also be transported by prevailing winds from railyards to residential areas.
