Doc #: 95 Title: Improving Emission Inventories for Effective Air Quality Management Across North America: A NARSTO Assessment | Document Link
Region: North America
Document Status: Unsubmitted, 2009/09/30
Parameters: trace gas, PM, NO2
Description of Document: Assessment has four functions: Identifies national, state, local inventories and provides access info. Describes methods used to generate emissions and discusses the strength and weakness of these methods. Directs considerable attention to methods for determining uncertainties in emissions estimates. Suggests ways to improve future inventories and improve data delivery of emission data to users.
- Chpt. 7 - Top-down
tests of emission inventories are tests conducted outside the structure of the emission inventory. They do not explicitly consider the individual components (e.g., emission factors or activity factors) that go into the development of inventories from the bottom up. Rather they consider independent information such as ambient measurements of the emitted species. Thus, a top-down approach can be thought of as an attempt to partially confi rm an inventory.
Satellite: Chpt. 6 - technologies Other techniques, including satellite remote sensing and inverse modeling, are relatively new to air pollution analysis, though the latter has experienced extensive application in other fi elds.
