Ranking the Performance of Climate Models for Summertime Sea Ice Simulation 19 January 2021

Ranking the Performance of Climate Models for Summertime Sea Ice Simulation

Researchers funded by both the CPO Climate Variability & Predictability (CVP) program and the Modeling, Analysis, Predictions and Projections (MAPP) program rank the performance of over 30 CMIP5/6 climate models in reproducing observed atmosphere-sea ice relationships.

Study Provides New Understanding of Plants, Droughts, and Climate Change to Improve Models 12 January 2021

Study Provides New Understanding of Plants, Droughts, and Climate Change to Improve Models

Building models that can appropriately capture plant-water interactions is critical in order to accurately simulate the onset and evolution of droughts and their cascading impacts throughout the Earth system.

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.
