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 US Southwest.

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.

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.

This study, funded in part by Atmospheric Chemistry, Carbon Cycle, & Climate (AC4), investigates the relationship between primary and secondary sources of organic aerosols over the lifetime of a wildfire plume, finding at least half of the secondary sources are the result of evaporation of the primary sources.

Researchers supported in part by CPO’s Atmospheric Chemistry, Carbon Cycle, & Climate (AC4) program have collected new aerosol data at two coastal sites on the North Slope of Alaska. Their work, combined with past data from NOAA, reveals that sulfur aerosol concentrations continue to increase at more than 2% per year.
