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.

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.

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.

Published as a NOAA Technical Report, this white paper identifies the NOAA mission requirements, stakeholder mandates, and seven science and operational application areas that will benefit from geostationary satellite instruments providing atmospheric composition products.
Atmospheric Chemistry, Carbon Cycle, & Climate (AC4)-funded researchers determine acyl peroxynitrate, one possible result from nitrogen oxide (NOx) reacting in the atmosphere, can act as a NOx sink rather than a reservoir in rural and remote forested regions.
Researchers funded in part by AC4 have developed a fire prediction model which incorporates multiple machine learning algorithms to better predict areas burned by wildfire in the US south central region.
The Los Angeles Basin is often thought of as a dry, smoggy, overdeveloped landscape. But a new study funded in part by CPO’s Atmospheric Chemistry, Carbon Cycle, and Climate Program shows that the manicured lawns, emerald golf courses and trees of America’s second-largest city have a surprisingly large influence on the city’s carbon emissions.
