Developing a Framework for Effective Air Quality Management

3.5 Understanding the Sources of Air Quality Problems

3.5.5 Quality Assurance
No discussion of inventory development or almost any air quality management component is complete without a discussion of quality control. The emission inventory creator must recognize that there is considerable potential for error to creep into an inventory. It is almost certain that some emission estimates will have less reliability than others. It is not uncommon to maintain an indicator of data reliability with each element of the emissions inventory so that later iterations of the inventory can take advantage of these indications to search out more reliable data.
