A new AC4-funded study on atmospheric ozone production uses field observations to investigate changes in ozone production on high ozone concentration days during the summer of 2018.
Using data from the FIREX-AQ field campaign, a new AC4-funded research study develops a comparison between aerosol concentration and the way aerosol particles scatter light in the atmosphere, offering new insights into wildfire smoke evolution.
CPO’s Atmospheric Chemistry, Carbon Cycle and Climate (AC4) Program is announcing 9 new 3-year and 2 new 2-year projects in Fiscal Year 2022 (FY22) that aim to increase our understanding of emission factor of fires and the composition and chemical transformation of wildfire smoke components from the wildland-urban interface. The selected projects total $6.3M1 in grants. Biomass burning
