The tropospheric distributions of chemically and radiatively important constituents such as ozone, water vapor, carbon dioxide, and aerosols are strongly influenced by transport, and quantifying this transport is central to understanding and predicting air quality and climate change. We are using trace gas measurements and model simulations to quantify the transit-time distribution (TTD) for transport from NH populated regions.
