Pollution Changes Clouds' Ice Crystal Genesis

PNNL found dust particle surface reshaped during atmospheric passage, altering ice-forming ability

November 2015
Researchers at PNNL found that miniscule particles of airborne dust, thought to be a perfect landing site for water vapor, are altered by the pollution they encounter in the atmosphere during their cross-continental journey. After modifying dust particles in the laboratory to mimic their encounter with pollution from vehicle exhaust and biomass burning, the team discovered some conditions favor cloud-ice-forming potential more than others.
