2020 journal article

Modeling stratospheric intrusion and trans-Pacific transport on tropospheric ozone using hemispheric CMAQ during April 2010-Part 1: Model evaluation and air mass characterization for stratosphere-troposphere transport

ATMOSPHERIC CHEMISTRY AND PHYSICS, 20(6), 3373–3396.

By: S. Itahashi*, R. Mathur *, C. Hogrefe * & Y. Zhang n

TL;DR: H-CMAQ is applied to study the stratospheric intrusion and trans-Pacific transport during April 2010 and a new air mass characterization method is developed to distinguish influences of stratosphere-troposphere transport (STT) from the effects of photochemistry on O3 levels, which can contribute to understanding the role of STT.

2020 journal article

Modeling stratospheric intrusion and trans-Pacific transport on tropospheric ozone using hemispheric CMAQ during April 2010-Part 2: Examination of emission impacts based on the higher-order decoupled direct method

ATMOSPHERIC CHEMISTRY AND PHYSICS, 20(6), 3397–3413.

By: S. Itahashi*, R. Mathur *, C. Hogrefe *, S. Napelenok* & Y. Zhang n

TL;DR: The analysis suggests that the impact of recent emission changes on changes in the contribution of trans-Pacific transport to US O3 levels was insignificant at the surface level and was small (less than 1ppbv) over the free troposphere. (via Semantic Scholar)
