The Criteria database was used to measure air quality based upon averaging direct measurements from monitoring stations located around the country. This series contains records that track those pollutants upon which an ambient standard, objective\n, or guideline has been established to protect human health and welfare. These National Ambient Air Quality Standards are set at levels that protect the public health and welfare from any known or anticipated adverse effects for the following criteria pollutants: ozone, carbon monoxide, nitrogen oxides, sulfur oxides, lead, and fine particulate matter. The Criteria database includes all point, area, mobile and biogenic sources of emissions. Emission sources are categorized by the source of the emission that emanates from it. Point sources are generally large grounded facilities that emit above a specified threshold. Area sources are facilities that do not qualify as point sources so they are combined together to represent the emissions of an industry. Mobile sources include moving vehicles or equipment. Biogenic emissions emanate from non-human sources, such as trees and vegetation. The Criteria database consists of five files that measure these six major pollutants in every state, the District of Columbia, Puerto Rico and the Virgin Islands. The files include Airdata, Standard Classification Code (SCC) annual, Standard Industrial Classification (SIC) annual, Tier 1 annual, and County Tier 1 and Tier 2. The Airdata file contains the emissions of pollutants for individual facilities for each county measured in tons. The SIC file contains th\ne emissions of pollutants according to the United States Department of Commerce's categorization of businesses by their product or services per county measured in tons. The SCC file contains the emissions of pollutants according to the Environmental Protection Agency's (EPA) classification code for the equipment or operation emitting pollutants for each county measured in tons. The Tier 1 annual file contains the emissions of pollutants according to the EPA's broad categories for the point, area, mobile, and biogenic emission sources per county measured in tons. The County Tier 1 and Tier 2 file contains the emissions of pollutants according to the EPA's Tier 2 codes. The Tier 2 codes divide each Tier 1 category into groupings based upon the business of the originator of the emissions, or upon the type of emission. Each record includes state and county, facility name and address, types of pollutants and the amount of emissions.\n
