"Using Measurements and Models to Improve Emissions Understanding" with Greg Frost, NOAA.

Emissions are key drivers to changes in atmospheric composition, air quality and climate. Accurate, timely, and complete emissions information is critical to environmental science and policy. Bottom-up inventories, the primary tools for quantifying and predicting emissions, have significant uncertainties that stem from the complexity and diversity of sources and from insufficient real-world data. Top-down emissions approaches leveraging atmospheric measurements and modeling provide objective evaluations of inventories and help to improve the scientific basis for emissions understanding. This presentation will highlight research by NOAA’s Earth System Research Laboratory and its collaborators aimed at top-down quantification of emissions and their impacts on atmospheric chemistry. Efforts to build a stronger global community for emissions science will also be discussed.
