About
N. I. Kristiansen is an atmospheric scientist whose research focuses on the long-range transport of volcanic aerosols and their impact on climate and air quality. Her most influential work centers on the Eyjafjallajökull eruption in April 2010, where she led a landmark study that combined Raman lidar and sunphotometer measurements to characterize aged volcanic particles over Athens, Greece. This highly cited paper (45 citations) provided unprecedented insight into the optical, microphysical, mass, and geometrical properties of volcanic ash and sulfate aerosols after days of atmospheric transport. By retrieving vertical profiles of extinction, backscatter, lidar ratio, and Ångström exponent, as well as mean effective radius and refractive index, Kristiansen demonstrated how synergy between active and passive remote sensing can reveal the evolution of volcanic plumes. Her work has been instrumental in improving aerosol transport models and aviation hazard assessments, showing that aged volcanic particles retain distinct signatures that can be tracked across continents. Through her careful observational analyses, Kristiansen has advanced our understanding of how volcanic emissions interact with radiation and clouds, making her a key figure in aerosol–climate research.
