New research demonstrates the presence of solid organic-coated ammonium sulfate particles in the Arctic boundary layer. As the Arctic loses ice, researchers expect to see more of these unique particles formed from oceanic emissions combined with ammonia from birds, that can change how clouds form and climate.
A new study funded by CPO’s AC4 program expands our understanding of the composition and sources of Arctic organic aerosols.
New research reveals the contribution of ⍺-pinene + NO3 in the secondary aerosol budget, and likely constitutes a major removal pathway of reactive nitrogen from the lower troposphere.
Atmospheric scientists, funded in part by CPO’s Atmospheric Chemistry, Carbon Cycle and Climate (AC4) program, developed an improved method to represent the removal of aerosols from the atmosphere in climate and air quality models.
Research led by MAPP supported PI, Dr. Suzana Camargo, examined the impact of volcanic aerosols on recent global tropical cyclone activity in observations, reanalysis, and models (including the CMIP5 multi-model).
