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.

Webinar: Overwhelmed? Reevaluating Stormwater Design in a Changing Climate

Join NOAA and the Water Research Foundation, along with four water management practitioners, to learn about reevaluating stormwater design and flooding management. These talks are highlights from the recent workshop series, “Climate and Weather Information for Small- and Medium-size Water Utilities.”

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.
