Air Toxic Emission Factor - The Air Toxic Emission Factor database was developed in Clipper for the EPA. It provides access to the airborne toxic criteria chemicals and their emission factors from various industrial processes.
Global Emission Inventory System - The Global Emission Inventory System was developed in dBASE for the EPA. It estimated and graphed the global emissions of six chemical groups based on known emission factors and industry production reports from the CIA. Industries were mapped with a latitude and longitude. Emissions were summarized, reported, and graphed at a 10x10 degree grid resolution.
Global Resource Emission Model - The Global Resource Emission Model was developed in Clipper for the EPA. It provided a friendly, customizable interface to the Global Emission Inventory System.
VOC/PM - The Volatile Organic Compound / Particulate Matter database was developed in Clipper for the EPA. It provided quick, easy access to the chemical speciation for every SIC (Standard Industrial Classification) and Source Classification Code.
XATEF - The Crosswalk / Air Toxic Emission Factor database was developed in Clipper for the EPA. It combined the Crosswalk and ATEF databases for a complete and thorough set of relationships between industries, processes, and toxic chemicals.
