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.

New Framework for Understanding Precipitation in CMIP6 Climate Model Simulations

In order to pinpoint the origins of precipitation biases in the most recent version of global climate models a team of researchers funded in part by CPO’s Climate Variability & Predictability (CVP) program developed a new framework to study the moisture budgets of the newest generation of global climate model simulations.

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

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

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.

Volcanic Eruptions and Coral Archives Guide Reconstruction of Past Tropical Pacific Climates

University of Washington researchers, funded in part by CPO’s Climate Observation and Monitoring (COM) program show that coral-only proxy reconstructions are more skillful with regards to tropical Pacific variability in the Nino 3.4 region (central, equatorial pacific) and show an unexpected climate responses to early 19th century volcanic eruptions.

U.S. Methane “Hotspot” is Snapshot of Local Pollution

Supported in part by CPO’s Atmospheric Chemistry, Carbon Cycle, and Climate (AC4) Program, scientists from two University of Colorado institutes and NOAA participated in an intensive field campaign that used instrumented aircraft and vans to investigate the causes or sources of a methane hotspot in the U.S. Southwest.
