Emission Inventory Improvement Program Volume 6: Quality Assurance Procedures and DARS Software Data Attribute Rating System (DARS) Support Software

DARS provides an overall confidence rating for an emissions inventory. Although the EPA originally developed DARS to assist in evaluating country level inventories of greenhouse gases that had been developed using area source methods, the system has been expanded so it can be applied to point source inventories as well.
