Comprehensive Summary of Reactive Oxidized Nitrogen Species in Western US Wildfire Smoke Plumes 12 January 2021

Comprehensive Summary of Reactive Oxidized Nitrogen Species in Western US Wildfire Smoke Plumes

A research team funded in part by CPO’s Atmospheric Chemistry, Carbon Cycle, & Climate (AC4) program observed and summarized the evolution of reactive oxidized nitrogen species in sampled from wildfire plumes as part of the Western Wildfire Experiment for Cloud Chemistry, Aerosol Absorption, and Nitrogen (WE-CAN) field campaign.

The Benefits of Measuring Greenhouse Gases using Light Rail Public Transit 22 December 2020

The Benefits of Measuring Greenhouse Gases using Light Rail Public Transit

Can semi-continuous carbon dioxide measurements taken from an instrument placed on top of a mobile light rail tram usefully improve urban emission estimates? Researchers, funded in part by CPO’s Atmospheric Chemistry, Carbon Cycle, & Climate (AC4) program, demonstrate not only that the measurements improve emission estimates but also that the measurements better capture spatial differences in emissions. 

Aircraft Measurements of Nitrogen May Lead to a Better Understanding of Wildfire Smoke and Air Quality 22 December 2020

Aircraft Measurements of Nitrogen May Lead to a Better Understanding of Wildfire Smoke and Air Quality

A research team, funded in part by CPO’s Atmospheric Chemistry, Carbon Cycle, & Climate (AC4) program, participated in the 2018 WE-CAN field campaign and used resulting emission samples from 23 wildfires to better understand reactive nitrogen in wildfire plumes in order to improve air quality forecasts.

Rising Temperatures and Better Cars: Ozone Production in the Los Angeles Basin 16 December 2020

Rising Temperatures and Better Cars: Ozone Production in the Los Angeles Basin

Funded in part by CPO’s Atmospheric Chemistry, Carbon Cycle, & Climate program, this study analyzed trends in two well-known precursors of ozone and their relationship to high ozone events in the Los Angeles basin over the last two decades. In particular, continued heat events will probably be associated with more high ozone events. 

Plant Physiology Plays Major Role in Ozone Uptake 15 December 2020

Plant Physiology Plays Major Role in Ozone Uptake

New study supported in part by CPO’s Atmospheric Chemistry, Carbon Cycle, & Climate program finds plant damage (including crop damage) from ozone may be greatest in years with high plant production, not necessarily years with high ozone.
