Atmospheric Ice-Nucleating Particles in the Dusty Tropical Atlantic
Desert dust is one of the most important atmospheric ice-nucleating aerosol species around the globe. However, there have been very few measurements of ice-nucleating particle (INP) concentrations in dusty air close to desert sources. In this study we report the concentration of INPs in dust laden air over the tropical Atlantic within a few days’ transport of one of the world’s most important a...
متن کاملExport of ice nucleating particles from a watershed
Ice nucleating particles (INP) active at a few degrees below 0°C are produced by a range of organisms and released into the environment. They may affect cloud properties and precipitation when becoming airborne. So far, our knowledge about sources of biological INP is based on grab samples of vegetation, soil or water studied in the laboratory. By combining measurements of INP concentrations in...
متن کاملRainfall drives atmospheric ice-nucleating particles in the coastal climate of southern Norway
Ice-nucleating particles (INPs) active at modest supercooling (e.g. −8 C; INP−8) can transform clouds from liquid to mixed phase, even at very small number concentrations (< 10 m−3). Over the course of 15 months, we found very similar patterns in weekly concentrations of INP−8 in PM10 (median= 1.7 m−3, maximum= 10.1 m−3) and weekly amounts of rainfall (median= 28 mm, maximum= 153 mm) at Birkene...
متن کاملRainfall drives atmospheric ice nucleating particles in the maritime climate of Southern Norway
Ice nucleating particles active at warm temperatures (e.g. -8 °C; INP-8) can transform clouds from liquid to mixedphase, even at very small number concentrations (<10 m). Over the course of 15 months, we found very similar patterns in weekly concentrations of INP-8 in PM10 (median = 1.7 m, maximum = 10.1 m) and weekly amounts of rainfall (median = 28 mm, maximum = 153 mm) at Birkenes, southern ...
متن کاملSingle-particle Characterization of Ice-nucleating Particles and Ice Particle Residuals Sampled by Three Different Techniques , Björn Nillius
In the present work, three different techniques to separate ice-nucleating particles (INP) as well as ice particle residuals (IPR) from non-ice-active particles are compared. The Ice Selective Inlet (ISI) and the Ice Counterflow Virtual Impactor (Ice-CVI) sample ice particles from mixed-phase clouds and allow after evaporation in the instrument for the analysis of the residuals. The Fast Ice Nu...
