Quantifying and Reducing Uncertainty in the Processes Controlling Tropospheric Ozone and OH

Project: Research

Description

This project will provide fresh scientific insight into the chemical and dynamical processes governing tropospheric OH and the related gases ozone and methane. It involves the development and application of new statistical approaches and uncertainty analysis to confront global chemistry-climate models with rigorous observational constraints. This will allow us to quantify the importance of different processes, explain the diversity in model assessments of past and future atmospheric composition change, and attribute observed changes to specific drivers.
