Emissions Inventory

One of the major challenges in atmospheric science is to improve emission inventories of environmentally deleterious gases. Bottom-up inventories based on understanding emission processes represent a considerable body of knowledge, but are inherently uncertain. Additional top-down constraints based on observations of trace gases are necessary to accurately represent spatial and temporal variations in emissions.

Objective: Evaluate and improve bottom-up emission inventories of NOx and SO2 with additional top-down information from satellite instruments through integrated analysis of aircraft and ground-based observations with global and regional models.
