Solid aerosols in Arctic atmosphere could impact cloud formation and climate

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.

New research provides insight into the abundance of natural and anthropogenic organic aerosols in the Arctic

A new study funded by CPO’s AC4 program expands our understanding of the composition and sources of Arctic organic aerosols.

Reaction of ⍺-pinene with nitrate is a major contributor in secondary organic aerosol formation 25 February 2022

Reaction of ⍺-pinene with nitrate is a major contributor in secondary organic aerosol formation

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.

PNAS Study Improves Representation of Dry Deposition in Climate and Air Quality Models 13 October 2020

PNAS Study Improves Representation of Dry Deposition in Climate and Air Quality Models

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.

Little evidence of reduced global tropical cyclone activity following recent volcanic eruptions 20 May 2019

Little evidence of reduced global tropical cyclone activity following recent volcanic eruptions

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).
