Investigating the Complex Science of Transport in Large-scale Ocean Currents

In representing the transport of ocean properties such as heat or salinity, the smaller, more complex details may matter significantly according to researchers funded in part by the Climate Variability & Predictability (CVP) program.

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.
