Seasonal impacts of ammonia emissions from animal feeding operations on air quality in northeastern Colorado

A recent study shows that high summer temperatures inhibit ammonium nitrate formation from ammonia emissions at animal feeding operations, potentially leading to high particulate matter levels in cooler seasons.

Revealing Brown Carbon Chromophores Produced in Reactions of Methylglyoxal with Ammonium Sulfate

Research supported by CPO’s Atmospheric Chemistry, Carbon Cycle, and Climate (AC4) program was recently published in the Journal Environmental Science and Technology. The paper by Lin et al. focuses on the poorly-understood formation mechanisms of atmospheric brown carbon (BrC) chromophores.
