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.

New Framework for Understanding Precipitation in CMIP6 Climate Model Simulations 12 January 2021

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 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.

How the Annual Wet/Dry Cycle Influences Daily Rainfall in the Maritime Continent 16 December 2020

How the Annual Wet/Dry Cycle Influences Daily Rainfall in the Maritime Continent

New study by researchers supported by CPO’s Climate Variability & Predictability (CVP) program investigates how the wet and dry seasons of the Maritime Continent impact daily precipitation cycles in the region.
