Rising Temperatures and Better Cars: Ozone Production in the Los Angeles Basin 16 December 2020

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. 

Plant Physiology Plays Major Role in Ozone Uptake 15 December 2020

Plant Physiology Plays Major Role in Ozone Uptake

New study supported in part by CPO’s Atmospheric Chemistry, Carbon Cycle, & Climate program finds plant damage (including crop damage) from ozone may be greatest in years with high plant production, not necessarily years with high ozone.

U.S. Methane “Hotspot” is Snapshot of Local Pollution 25 November 2020

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. 

Long-Term Field Observations Lead to New Insights in the Formation of Organic Aerosols 24 November 2020

Long-Term Field Observations Lead to New Insights in the Formation of Organic Aerosols

Research funded by two AC4 awards used observations from three long-term networks to update or “constrain” the chemical transport model mechanisms to more accurately represent the indirect formation and month-to-month variability of organic aerosol in the US southeast. 

Predicting the Mass Concentration of Black Carbon in the Atmosphere 17 November 2020

Predicting the Mass Concentration of Black Carbon in the Atmosphere

Relying on both classical statistical techniques as well as new machine learning approaches, this project funded in part by Atmospheric Chemistry, Carbon Cycle, & Climate presents a new model for predicting the mass of black carbon in the atmosphere that can be used with inputs commonly collected at most long-term monitoring sites.
